Has anyone been experiencing bad battery life on the g2? When i first got it a month ago it was amazing easily getting 50+ hours with about 6 hours screen time. But over time its been getting worse. I already did the whole stopping the carrier iq and all that, it still doesnt help much. Now when i go to sleep and wake up 7-8 hours later my battery drains 50% or something like that for no reason, no wifi or anything on or synced. I did see some posts about people experiencing bad battery, this phone is supposed to have amazing battery life whats going on? I rooted my phone, still on stock rom, wondering if anyone has fixed their battery issue. Would installing a new rom like aeon v3 help improve battery like its supposed to be? Its getting frustrating, my gs4 had worse battery but at least the standby times werent as bad as they are on my g2. Any fixes for this?
There has to be something running in the back ground draining battery. If not try finding a battery Conditioning Application
Sent from my LG-D801 using xda app-developers app
Based on the above it could be a few things.
If you want to check a few things on the phone side you can:
- install GSAM Battery and let it keep an eye on what's actually using your juice. Then either remove, modify, adjust settings, etc, for whatever is using it. If it's an app... delete it. Reinstall it.
- You can try a factory reset
If neither fix it then you can try another ROM, but if your battery is just as bad with a factory reset I'd lean towards the battery. Maybe you have some bad cells.
I've had mine for a bit, and I only lose a little bit if not touched overnight.
My current setup:
- Madhi 4.4 KK ROM (1/18 build)
- Obviously rooted with the above
- Greenify on all my non-necessary apps (hangouts, weather and one other app spared from this)
- All my apps auto-sync features are disabled since I just run it once in a while, and things like mail / etc I don't need push anyways
I get pretty solid life even after a few moths of use now.

first, install betterbatterystats and look for wakelocks, try reseting the device. batterylife also depends on how you use the phone...i can get 9hrs on screen time reading books with still 15% left or drain it in 3-4hrs playing games.

Yes i have downloaded and used gsam battery app. I dont see anything unusual in my stats, also using better battery stats, its been in deep sleep for most of the time, and it doesnt say the phone was on or running when the screen was off. But for some reason i wake up and my battery is decreased by 50% again....I am using greenify and hibernating alot of those annoying apps. I am stopping apps that are running . And on the phones battery manager android system is first with 34% but it says its only been running 11min, and no gps is listed. And my screen on time was 2 hours those are what i foudn when i woke up with 20% left, at night it was 70%. I seriously think my phone is messed up when im using it its not that bad, but for some reason when i go to sleep and leave it alone it dies for no reason....

Ah i am using better battery stats, and nothing seems to be out of the ordinary, its been in deep asleep for most of the time. And the phone doesn't say to be on when it wasnt supposed to. Same thing on the phone battery manager it says android system is 34% with 11min being on,and screen is 2 hours. When i woke up my battery went form 70 to 20%.....i am using greenify, and stopping running processes, like carrier iq an other apps. i dont know whats wrong...this is getting frustrating, i have also factory my phone already, it was fine for a few days but now its constantly draining like crazy at night...i love this phone, but i think mine might be messed up! You think changing the rom would make it go back to normal? Even though my phone isnt supposed to be behaving like this with stock...

I definetly would try it. Also you could try different kernel. But its beginning to sound like there could be a defect in your battery. If nothing helps i would send the phone to LG and let the battery replace. You are still in warranty, right?

my battery has a problem too..
when my phone is idle sometimes the battery level increases by 1 or 2.
when im playing heavy games like gangstar 4 the battery decreases every 2 mins and the temperature reaches 40°C. and when im just browsing it decreases every 3-5 mins with a temperature of 34-36°C. and when im watching kuroko no basket (wifi off) every episode just consume 2-3% of the battery (24 mins. = 2-3%)
and the temperature is about 28-30°C.
I think my battery drain problem depends on the temperature
Hello guys!.It's my first time here. So, I have some questions regarding this problem
I bought my S7E around july, and it had amazing battery life, It lasted around 30hours++ but I drained the battery by playing games so I can charge my phone before 5pm(my office hours) to avoid over charging when I go to bed. I even used the best perfomance that time, gps on, gestures on, etc.But still at least it lasted for 27hours.Now, it only lasts for about 12 hours something. Ive never overcharged it. The moment I saw the green led, i plugged off the charger.
Can anyone fix this? well please don't tell me to turn off all the features, I had them on and still I got to use 27hours. I dont know when I did the update, maybe os 6.0.1 is draining the battery?or any suggestion?
Thank you
Go to Settings>Battery and view the usage to see what app is using it much battery.
You can NOT overcharge the battery of your S7 Edge. I've always kept my phones on the charger over night and never had problems. I'm doing that since the HTC Magic (T-Mobile G1). It has overcharge protection. It is NOT good to drain a Lithium-Ion battery down to a few %. A Lithium-Ion battery operates the best when charged >40% and at average room temperature.

Nope. I never drain my battery.I keep my battery until 20% then charge it directly. I know how to take care of Lion battery. Ive heard about the overcharging protection feature but i'm not sure whether it works.we never know whether that program runs on background or not since we cant track it.

Well, then don't charge overnight. You're problem is most likely software related anyway unless your battery is very old and/or you overstressed the battery too often which can't be because the S7 Edge isn't that old and you "...know how to take care of Lion battery". I think you meant Li-Ion but w/e. A defective battery is possible but very unlikely. BTW overcharge protection is not a program. It's a physical thing soldered onto the battery/charger PCB. Hardware. There's one built into the battery and one inside the charger and of course we can track it. You can't because you probably don't have the equipment + knowledge to test it. If you're so concerned, you should really read about it. After all, you're dealing with a highly reactive metal.

Well that's why i charge my phone at my office:crying:
i wonder if the OS is the problem. I've heard about drivers not compatible on s7 using 6.0.1 so the background data keeps working such as gear vr service. It wasnt there before. and OM Customize. So, if i overstressed my battery, it will damage my battery? I did that before to charge my phone between morning to evening.

You're hearing really weird things buddy The S7 Edge has always been running Android 6.x.x. It never ran any other Android version. The drivers are fully compatible. In fact, the drivers on a Samsung are as compatible as drivers can get, since SoC, Camera Sensor and many other parts of the phone are coming from the same manufacturer; Samsung.
My guess, and I can only guess since we'd have to see your battery stats for more detailed explanations, is that you either ran into the Android System-, or Google Play Services battery drain bug that occurs after an OTA update. These problems date back all the way back to the Galaxy S2.
I'd recommend you first flash a stock ROM using the "HOME_CSC" file. This will NOT wipe anything from your phone. Only the core system and stuff will be reinstalled. If you still have this problem, try flashing a stock firmware using the regular "CSC" file. Always make a backup first. The regular CSC file will WIPE EVERYTHING from your phone, including internal storage but it won't touch you MicroSD. Now you start with a freshly installed Android and see if it solved your problem.

Hello mate,I am sorry for my late reply since I gave up. I am trying to solve this again.
Well, can you tell me where can i get the stock firmware? I am from Indonesia(well I think some parts of the continents have different firmware).I wanted to flash it tho but I am afraid I got some "hacked" firmware.
well,the battery usage looks normal to me.
google play services around 5-15%
android OS 15-20%
android system 15-20%
but still,it drains too much>,<
Let me try to upload a pict of it.
Additional information : Slept 8 hours while listening to music and it drained from 55% to 2%.I mean this is really insane.That's why I am taking serious action now. The first time I bought it with the same settings and apps + I turned on always on display and night clock while listening to the music for 8 hours of sleeping,it only drains 10-20%.
I took this ss because I got 30hours on time : link
these are the drained ones.15Nov and 9 Dec
15Nov
9Dec
Thank you mate
First out of all. How much SOT (Screen On Time) do You get?
To check that go to battery usage at the end of the day or when You have 20% and in battery usage tap on screen and take a screenshot.
Second.
Certain firmware updates decrease battery life a little.
And third.
You can disable apps that are draining Your battery if You don't need them.
Also for a really good battery info what uses Your battery etc You can download GSAM battery monitor from play store.

well from the time being, i think my network operator is draining my battery.I tried to turn off my mobile network last night and used wifi instead.I lost 1% for 8 hours.Well, I changed my network operator around october and since then I felt the battery drain. I already sent report to the provider hope they solve it.
But I wonder, my network operator has good 4g coverage here, why does it drain too much? My old operator had only 3g coverage.Is there any way for me to track down my operator whether they are using too much battery to search network coverage maybe?
Newest firmware always decrease battery life a little
Hello and Happy New Year to all,
*
I came across an issue with my Note's (N910C) battery today and I would like your opinion on it.
*
A quick background:
*
The phone has never been rooted.
9-10 months ago I downloaded an official firmware (6.0.1) which I flashed via Odin and it began to drain the battery very fast, killing the phone in less than a day.
I got a new battery, but the problem was still there.
Eventually I tried another firmware which worked nicely and consumption returned to normal levels. Since then, I had no problems whatsoever.
Yesterday night I got a notification to update. I had already done another two in the past - if I'm not mistaken - , without noticeable difference.
I did the update overnight and I removed the charging cable in the morning. It seemed that it was a little warmer than usual, but I did not pay attention.
The battery percentage was reducing at the rate of 1% per minute and it died within 2 hours.
I checked battery info, nothing abnormal.
I have two questions:
*
1. Does anyone have similar experience with this model (or other)?
2. If I reinstall the previous firmware, normally the problem should be fixed, right? I mean it started after an official update which AFAIK affects native apps only.
*
Thank you in advance
I have noticed on my Note 4, after upgrading to marshmallow, the battery drained like crazy too. It would drain 10-20% when I use it for 20 mins or so. The battery that I'm using is a 'new' one that I bought just about a year ago although the problem still occurred when it was fairly new.
I'm speculating that there might be some sort of battery or software issue with marshmallow as the original battery that came with the phone also had the same issue. It would drain fairly quickly until one day it just stopped working and would boot loop until I plugged it in to the charger.
Ever since marshmallow, I have never seen my battery get to 15% before switching off completely. Sometimes even 45% lol.

I had a faulty N910F and got another (used) one and it's had occasional forced closes at between 15-20%. This worries me that it might go the way of the old one where it developed the issues with it freezing and the frequent reboots....does yours exhibit any other issues?

Yes. Unfortunately. Currently, it would just die halfway even when I'm at 50%? That's the highest that I've noticed. So I had to charge it up for a bit maybe to 60% and it would be fine before dying around the 20+ - 40% mark. Previously, the original battery that came with the phone had this weird issue where the battery won't hold any charge even when it's fully charged. Like it will go to a bootloop when I've unplugged it even though it's at 100%. When I bought the new, current battery I noticed that it would still die off at 15-20% and the original battery became bloated a few months later.
Are you using any custom roms? The bootloops and freezing could be related to using some custom roms. I changed from a N7 port to a deodexed stock rom and the frequency of the freezing and reboots just plummeted. Reboots only happening when the battery is close to dying.

Ah right, so you had only the reboots, nothing else? That's fair enough.
No, it's nothing at all to do with the ROM. I'm stock but LOTS of people have had the same issue. As it stands, the only way to fix it is to get a new mobo :crying:

Well besides the usual overheating that's related to our snapdragon CPU, nothing much but mostly battery issues.
Although there is thread that I'm following that promises to fix the 15-20% issue. Checking their method to see if it works or not

I had a similar problem with fast battery drain - did a factory reset and it's back to normal. Make sure you're using a battery from a reputable source like RavPower (don't think there are any genuine Samsung ones left and Anker stopped making them).

Hi, guys. I recently bought a new battery for my 1+ two and after replacing it I've been having some problems. The battery life is actually lower than before and some times my phone suddenly turns off. Is there some way to calibrate or recalibrate a new battery or something I can do to fix this?
First of all, is your battery an official one or a third party battery? If its an official battery, check the manufacturing date. I'm not sure if oneplus is still producing/selling oneplus 2 batteries; it could be quite old. If its a third party battery, then I'd say its fake and of bad quality.
Yeah, I got one too. Manufacturing date is March 2017, and mine is also pretty bad. The turn-off thing happened once to me. But it really seems weaker than the original one. I thought that it needed time to go up to its full potential, but it's been 2 weeks and it's not good. Either we go back to the original battery or we go for a new phone.
Exactly the same problem. You are not alone. I went out yesterday and it just turned itself off and i couldn't turn it on . Didn't have a phone for 5 hours. And not only that MTP doesn't work (I'm not blaming the battery of course). It's not even showing as an unknown device in the device manager I wanted to perform a format, flashing an img via fastboot and I can't. #neveragain
Ok, so I bought a new battery because this one started to drop really fast. I got one from Ebay for $15 (last one was 30 from amazon) and it came really fast and visually it looks exactly like my original battery (the amazon one looked a bit different) only the manufacturing date is 03/2017. SO when I tried to remove the current battery, the connector got stuck to the socket. And I really tought that was going to be the end of this phone, but I removed it after some trying and put the new battery. Hope this one is better, if not I'll go for a new phone.
I recently bought a new battery from here:
https://www.replacebase.co.uk/oneplus-two-replacement-internal-battery-3300mah-fa-p597-original/
They claim its an 'OEM' battery, but its quite clearly a knockoff.
I also experienced some of the issues mentioned in this thread:
Phone powering off when fully charged (80-90% capacity) - and not powering on again until I plug into mains
Fast discharge - I'd struggle to get 12 hours out of a full charge, even with minimal screen-on time.
I'm not entirely sure whether the fast drain and phone powering off was related to the OS / Kernel I was using. For a long time I was using the lineage nightlies, recently I moved to Francos Kernel and also installed the flashable 'v3' zip from this thread: - https://forum.xda-developers.com/oneplus-2/general/power-tweaks-snapdragon-810-devices-t3261790 - which definitely looks to have reduced the idle drain and overall drain quite a lot. Also my phone no longer turns off randomly.
Additionally:
Removed all widgets
Turned off ambient display, turned brightness down
Turned off all gestures
Prevented facebook app from running in background - https://www.xda-developers.com/runinbackgroundsetter-restrict-background-processes/
I need to switch back to my original battery to see if I get better performance than the 'OEM' battery I bought - as potentially the battery drain issues I was having before were purely down to the software / kernel
edit: - still getting phone shutdowns with the 'OEM' replacement battery. Currently using https://www.cmxlog.com/14.1/oneplus2/#lineage-14.1-20170831-nightly-oneplus2-signed.zip and Franco Kernal r11

Since it was used, I also got one of the extended life 4100Mah batteries to hopefully make it last at least the entire day without topping off the charge. She usually averages around 4 - 5 hour SOT, so this seemed like a good option from what I've read, and fits in the original door so I can use the wallet case she wants with it.
But man, her battery life is TERRIBLE! I checked with Accubattery, and it reports that the battery is charging within 99% of it's 4100mah spec, so I don't think its a bad battery. Yet, she can barely go 12 hours with just under 2 hours SOT before the phone dies!
She is unrooted, running stock Oreo.
I installed GSam Battery Monitor and used their ADB commands to give it permission to record deep statistics w/out root (pretty cool, never did that before). I ran it for a little while this morning. Within 3 hours 40 minutes off the charger, she was already down to 72% with barely any SOT. I'm attaching screenshots of the app usage and doze screen (sorry for the phone-snapped-of-phone picture, it's my wifes phone like I said, so it was easier to just snap with my camera than take a screenshot and send it to myself to post).
Maybe I'm not reading this right, but it seems like something is keeping her phone from sleeping. A big culprit seems to be call services, and in my location settings, I noticed it mention that LG IMS was doing a lot of heavy battery drain with location related inquiries.
I thought maybe it was related to WiFi calling, so I turned that off. Cell reception is average.
2 hours later, she's down to 50% so that wasn't it. I don't know what else to try other than hard reset, but we literally just got this and set it up 2 days ago, and its been like this from day one. I don't see why it would be any different the second time around.
It's likely a junk battery. It's really hard to get a good oem replacement battery.
If you shop Amazon look for a Taeozi 4200 or Shemnz 4200. They both have 2 year warranty and decent reviews here on XDA
The Perfine 4100 is also highly recommend
Any Li-polymer should be better

When I bought my wife's phone it had a battery drain/overheat and wakelock issue as well. I fixed it and haven't had an issue since. Here's what I did to fix it:

I did my homework first and got the Perfine from Amazon, not a no-name junk battery. When I couldn't fit it without removing the sticker, the seller was really helpful and actually offered to replace it after checking first that it fit in *THEIR* V20 at the factory. Really solid customer support. And according to Accubattery, it really is the capacity it says. Or at least within 99% of it (I think it estimated 4080 or something like that). So I don't think that's the issue.

That's actually really interesting- I did take apart the phone to do the thermal mod thing (wiped off the dried up pink gunk and put a thermal pad there), but it seemed pretty clean otherwise inside when I did. How on earth did you figure out that was the problem?
After speaking with some folks on Telegram, Reddit, and other corners of the internet, I have a different theory. A bunch of people told me to let the rom "settle", that battery life is never good after a fresh format or new rom flash. Honestly, the critical thinker in me says that sounds like nonsense. I've never heard of this before and I've been flashing roms for the better half of a decade. I'd think after it takes the time the load up your apps and settings and configure itself, it would be done. But I Googled it, and it seems to be a hotly debated subject.
Those that swear by it claim that whenever you start fresh or flash a new rom, it takes anywhere from one to a few battery cycles before the kernel calms down. Perhaps it is doing some sort of internal calibration based on your battery life and system demands or something like that. The theory seems to be that the Kernel doesn't allow the CPU to fully doze until it is done with this process, which sometimes takes days. I don't know, but the more I read about it, the more it sort of started sound plausible. When I got the phone, I tried out some things on it myself without a SIM card first, just to make sure everything on it checked out before giving it to the wife. Then, I did a hard reset, popped in her SIM card and let it do its thing. That's when we realized battery life was pretty terrible, as after 10-12 hours she already needed to charge... and this was on the 4100mah perfine!
I tried another hard reset, and when that didn't fix it, I decided it was time to root and see if I could get to the bottom of the bad battery. It seemed the kernel was where a lot of it currently went according to battery stat apps. After downgrading my H918 to Nougat so I could install TWRP, I promptly flashed Alpha Omega Oreo 20H and restored her apps. Turns out the next morning we couldn't sync her smartwatch, somehow we broke bluetooth (going into BT settings would crash the phone everytime). So weird, and while we were at it the battery life still wasn't great. So I did a hard reset that evening and found that even with nothing installed, BT was borked. (looking back at it, I think I should have flashed an Oreo rom like the stock 20H rooted first, and THEN the AO rom. I think going straight from nougat might have led to a driver mismatch or something)
Anyway, after that didn't work I flashed the stock rooted 20H rom, and lo and behold bluetooth and everything else is working again! But the battery has been bad all along and is still doing its generally suckiness thing.
BUT... as someone pointed out, if this kernel settle thing is real, I've been pretty much flashing and resetting this thing every other day. If roms need to "settle" first (still a debatable subject), than I never really gave it a chance yet and that's why I'm constantly seeing battery drain from things like Kernel even on different roms! And @pistacios, is it possible that you were having a kernel do the same thing since it was just reset and it just so happened to be that when it calibrated itself you thought you had fixed it by cleaning out the USB port?
All I know is I'm going to give this a couple of days before deciding on a plan B. Seems too simple to be the reason, but hey- I'm desperate.

Ive experienced ROMs settling in and battery stabilizing after a few days. But this was pretty far back with the HTC M7 and M8. Most modern phone's I've flashed pretty well settled in within the first few hours. The battery life on this phone was never amazing. It was good to just Ok for most when it was new.
If you flashed the stock rooted rom and still had bad battery life, I still suspect the battery itself. I still recommend one of the battery I listed earlier. If the perfine didn't work out try a different one.

Right, with the stock 3200mah battery. With the Perfine 4100, a lot of reports are saying 6-7 hours SOT or at least a full day of regular use. That's good enough, really. Mine is dying at half of that. I'm wondering if I have faulty hardware. I could put the stock battery back in and see if it dies much sooner.
I'm actually wondering if someone can check their mA use per hour with the screen on vs off, and I can see if the numbers make sense on mine. Accubattery is pretty good at the math.

Phone was up and running for 2 weeks, so it wasn't due to fresh reset.
GSAM battery monitor showed kennel wakelock, something about USB OTG in the top of the list, so I figured the port was my first check for a problem, and it was. It wasn't obvious that there was dirt or foreign matter in there, because it looked clean. But sure enough, after the light brushing with 94% alcohol, the problem disappeared.
I'm not saying this is definitely your problem, just throwing it out there.
