HTC One M8 battery drain: what’s causing it and how to fix it

The HTC One M8 is one of the best smartphones on the market, even if it already received a successor in the form of the HTC One M9. Although a good number of One M8 users already have Android 5.0 Lollipop and a new Sense 6 UI on their device, they are still experiencing battery drain. The battery drain problem on the HTC One M8 has been a persistent one of both Android 4.4.4 KitKat and Android 5.0 Lollipop. Users of the device have complained that their battery life dropped dramatically, especially after updating to Android 5.0 Lollipop. We’ve scoured the forums to find a few easy solutions to the problems and identify what is causing the battery drain in the first place.

A particular user complained on a forum that their HTC One M8 suffered a dramatic change in battery life after installing Android 5.0 Lollipop: from 48 hours of light use to 18 hours of virtually no use a day as a test. That dramatic drop is alarming for users, and with good reason, as phones should not have their batteries drained so much with no user interference. The culprit for this massive battery drain is surprising, and is actually a mixture between human error and app malfunction. When somebody has battery drain issues on their phone, regardless if it is an HTC One M8 or not, they tend to install battery monitoring and saving applications and they are prone to checking their phone every 5 minutes to see how much of the battery has drained. That combination is not a good one if your battery life has suddenly dropped.

First off, waking your phone up that often takes its toll on the juicer within, so refrain from monitoring your phone that much. Secondly, battery monitoring apps usually do more harm than good because they wake your phone up more often and tend to consume a lot of power while doing their calculations and tweaks. As these kinds of third party apps usually come with optimizing tools, they can interfere with the way in which Android 5.0 Lollipop works on your HTC One M8. That’s most likely caused by the fact that these apps haven’t been optimized for the new operating system, but it could also be bad app design in general, depending on where you get the app from. The easiest fix for this is removing the app and refraining from waking your phone up too often just to check the battery level.

Battery Doctor was one of the apps people found as the culprit for battery drain on the HTC One M8, because it wasn’t optimized for Lollipop. The app actually stopped apps in their tracks, but since it wasn’t configured properly, it stopped apps that Lollipop would just restart quickly after. That means that your phone was constantly being woken up as apps were constantly restarting. Removing these kinds of apps or replacing them with ones that are optimized for the HTC One M8 on Android 5.0 Lollipop is the easiest solution. I would recommend avoiding all types of battery apps, but there certainly are good ones out there.

Another surprising culprit for battery drain on the HTC One M8 is the alarm clock, because it keeps waking the system up to check if it needs to sound off an alarm. While that shouldn’t drain the battery too much, if you can’t find another explanation for your problem it might be better to avoid setting alarms on your phone for a while, until you get Android 5.1 and Sense 7.0, which will hopefully fix things. The usual fix for this kind of problem with battery life would be removing Facebook, Skype and other third party apps that use location services, push notifications and a constant internet connection to feed you your notifications. It’s just that simple, although not very convenient for social media buffs. I’ve found that since uninstalling Facebook and leaving only the Messenger app helped a ton with my HTC One M8 battery drain problem. It’s a small fix, but it can do wonders. If all else fails, start in safe mode, see if the issue is mended. If it is, then it’s definitely a third party app causing you trouble. See what uses the battery the most and uninstall it, or keep uninstalling things until you see an improvement.

My life-long dream has been to test out every gadget on the market! Considering the fact that I've rapidly destroyed almost every gadget I've had so far, I'm not inclined to owning something, so my ideal outcome would be to have a different gadget each month. I'm really into smartphones, wearables and tablets and I love Playstation and Xbox, I'm sure I'll beat you at your own game (after a month of training... or two)

  1. Isn’t Facebook a system app? If so, how can it be uninstalled?

  2. This article is a pretty big disappointment based on the title. It makes generic assumptions and provides no real answers. Waste of time reading it. For the record, I don’t do any of the stuff above, nor have I changed my usage of the phone since having 4.4.4, and my battery is dying faster on 5.0

    • Fwiw, I’ve seen huge improvements since I started using the Llama app. I set two actions. When screen is turned off(and mobile hotshot is off) turn off mobile data. When screen is turned on (and WiFi is off) turn on mobile data.
      Keeping mobile data off while I’m not using my phone has been the biggest help to my battery I’ve ever seen. Other apps like Tasker can do this, or you can do it on your own.. But Llama is free and easy.

      • I would suggest doing these things manually, in order to avoid another app consuming resources, but I haven’t tried Llama so far, so I can’t say if it’s a resource-eater or not. Tasker is pretty light-weight, though!

    • I’m sorry you feel that way! The article addresses the most common causes of battery drain and all the fixes I’ve found for them that work with Lollipop. If the software is at fault. the best tip I can come up with esides the generic factory reset is flashing the update or a custom ROM. Once again. Or wait for Android 5.1. what type of suggestions where you expecting? I’m asking because there aren’t that many different roads you can take when it comes to battery problems on any phone.

      • I perhaps came off a little harsh with the disappointment statement. I said that in regards to the title because the title insinuates that you know the one real cause which I expected to be a system thing, and so I clicked the link to here because I was interested in hearing that answer. In general, the article provides some good info on how to manage your battery life better, but the title should be something that applies to all Androids instead of the m8.

        • Oh! I get it know! I didn’t realize that, honestly! I can’t change it now, but I’m sorry you feel mislead. I didn’t even think of what you did when coming up with the title, I was referring to multiple causes and fixes, but you’re right. It does seem a bit misleading if you think of it that way. I’ll be keeping this observation in mind when writing articles in the future, clickbait is never good for either party. For all I know, there could be a software bug that causes the battery drain, but so far, reports from One M8 users aren’t that overwhelming and the issue seems to be sporadic, so it’s more likely related to smaller specifics, like bloatware not being compatible. But that’s just my guess.

          • I was also greatly disappointed as I have a serious battery issue and all the things Emily mentioned did not apply to my situation. My M9 is 4 months old. On top of many problems, I have this battery draining one. 2 days ago I charged for 30 hours, the level from 15% to 48 % 24 hours afterwards. I continue charging it for 6 or 7 hours. The level decreased from 48% to 11%. The carrier. T-Mobile, told me to buy another battery. Or trade in the phone and get a credit of $175. They would not replace my battery. I then tried to see if there were answers to find online.

          • It’s the tmobile software, their software causes all kinds of issues with the android os and drains the battery and i’m even partial to believing they’ve installed some kind of background battery draining software, but you’ll notice you can’t shut that app off and there are some apps on your phone that can’t be uninstalled either, because of them.

          • Thank you for pointing that out. I never thought about that. T-Mobile is the only carrier I have ever used, since the non-smart phone days a long time ago. I thought their price was good and service was fair. I have never given myself a chance to compare.

            May be their service is not good at all. In fact I had a great deal of difficulties with their service. I just thought it was normal with these companies.

    • Every new android system update will come with bigger usage of the battery (basic knowledge). There are many apps that helps optimize you phone. And the article is quite good and points out to very good apps.

      • I do not think you read the article correctly…
        The author points out that those apps are more often the cause rather than the solution. Also, I do agree with the author about most of it being poorly optimized apps.

        • Thanks. As the Lollipop rollout broadens, I think most popular apps will get optimized in due time. I wonder if those that aren’t that popular will follow. There are many very good apps in the Google Play Store which don’t really get the attention they deserve.

      • Thank you, although I don’t recommend using apps to optimize battery, just tricks and tips on how to minimize battery use. You are definitely right with software updates requiring extra power after install, but a reboot should fix that. If it doesn’t, it’s time to dig deeper!

    • Agreed, what a ridiculous headline. There is a REAL problem happening and the responsibility is NOT on the user!

      • Something I’ve noticed is that when my battery drains randomly, cell standby is the culprit according to the battery usage chart in settings. I wonder if this is a repeat of the radio issue the m7 was seeing and even the m8 had early on. I’ve been toggling airplane mode, r rebooting the phone, and seeing some relief.

        • sounds like your mobile carrier is trolling people’s phones by throttling the signal’s output or there is a defect in the receiver on this phone.

  3. I will admit that I, too, had battery issues when upgrading to Lollipop but I ended up doing a factory reset and my battery is now better than ever. Seriously. I know this sounds generic or whatever but it’s true. I was even hesitant to perform it but I’m glad I did. I backed up everything beforehand and I didn’t lose a thing. I have read that when doing a major upgrade on Android such as going from Kit Kat to Lollipop there are junk files that may not be compatible or needed in the new version of the OS that need to be discarded that only a factory reset can do. Now I’M NOT saying this is true, but only what I’ve read, and in all honesty, the factory reset helped me.

    • Thanks for the recommendation, I’m a bit relunctant to reset the phone but maybe I will try. I too am feeling a big battery drain since updating to lollipop, very disappointing because I was hoping for battery improvements with the update. Battery for the m8 use to be fine imo, the update has made it bad, and charging the phone seems to take longer too.

      • One thing I would suggest before doing a factory reset, is plain rebooting the phone, Usually, after installing a software update, the battery is affected for whatever reason, but I’ve found that a simple reboot helps in some cases. It’s worth a try, I suppose.

        • I had no battery issues until the update, now ” mobile radio active” is killing the battery. Overnight, no checking the phone, it went from 97% to. 55% … I did a simple reboot, didn’t help at all … No one had the answer to this and many people are having same issue

          • My battery level went from 15% to 48% to 11% in the course of 30 hours or charging. Yours also decreased. I thought mine was the only strange case.

    • I honestly didn’t suggest a factory reset because many are reluctant to do it, but I think what you’re saying is true. I don’t know about the junk files, really, but it’s definitely a possibility!

    • The T-Mobile technician was going to do a factory reset for my phone. But he was not able to save my contact info. So he did not do the reset. How do I back up everything when the professional technician could not? Seriously, can you teach me?

  4. Well that’s 2 minutes of my life wasted…

    • If you knew about battery apps doing the opposite of what they’re supposed to do, Facebook keeping your phone awake and the rest of the suggestions and issues, then it might have been. Do you have any suggestions which might be helpful?

  5. Literally the worst help ever. Why not just say, ” keep your phone off” to save battery?

  6. The new One M8 is beautifully design and constructed, is fast and has a great display, uses one of the best manufacturer-customized interfaces we’ve seen in recent time, and delivers all that without demanding compromise on battery life.

  7. I too had huge battery issues with m8 after lollipop installation. Was none of the stuff in the article. Just switch off Google location services. Made an immediate300% difference.
