I am having severe drain issues.
I used to get around 4-5 hours SoT and a day's worth of batter till 2months back.
Now I get 25% drain overnight and my battery barely lasts till 6PM everyday. This is after I put it off charge at 8 AM.

I do have a lot of apps and my GPS is generally on, but dozing is not prevalent.
Battery stats suggest that it's Android System and Android OS which eat the battery. They're always 40% of the app usage, atleast.
There's no way to understand what exactly within the Android processes is eating the battery.

I have disabled a few apps and my phone is stock ROM with NO Rooting.
I use Greenify sometimes and I prefer to restart otherwise.

Please help me

Reboot in recovery and clear cache, if it doesnt work check if some of your apps is keeping your phone awake. Ans last try is a factory reset, it will surely solve your problem.

After months of playing around I finally got some better battery life. SoT is a bit low but the battery last pretty long so I'm happy.

Screenshot_20170605-220228.pngScreenshot_20170605-220228.png

What I did
- 4.14 OOS
- greenify in shadow mode
- nap time
- disable system doze mode
- wakeblock app to block the annoying wake locks.

After that battery has been pretty awesome

Hi,
Can you share wakeblock zip that you flashed and apk that you installed that works on 1+3/t? Or direct me where I can find them?

Hi guys,
i'm having a big battery problem here, 1.30' SOT, and severe drain, i've made some screenshot:





Tried to clear cache in recovery, tried also AKT script, (altought i've got a lot of "permission denied" during script execution) but nothing changed, i'm with 4.1.3, rooted kernel stock, i think i have to reset it.....

I am having the same problem until the update to android 7.

Get BBS, its easier to read what is causing the problem


Does this app work on oos? Getting this error

For me not working.

Yup, only works on OOS 4.13 tho. the old core doesn't support 4.15. Hoping OP can add this into his rom :)

Hi, anyone knows where can I get a original battery of OP3?
Right now I get 2-2:30 SOT...

When I bought it I remember 5-5:30 SOT isn't even a year and the capacity now is less than half...

    Before you start looking for replacement phone/battery and such, I would recommend to flash a clean rom (preferably an official one with stock kernel and proper firmware) and live with just the bare set of included apps for couple of days monitoring the battery stats. In most cases you would find that the battery is just fine.
    In my little research, I found that many apps/configurations/incompatibilities of some sort can really eat up all the juice vary fast. That would be a software issue. Checkout attached images. That's over 3.5 days on battery, 5.5h sot and 40min calls. That's a light use, but result is still very good. In this scenario it is not a fresh installation, location is on all the time, sync is on, no battery saver mode or any tricks, but I have frozen most of the social apps (FB messenger, viber, skype, whatsapp) and some other apps. The problem was that earlier, my battery was being eaten way too fast. Phone had poor deep sleep, too much idle use etc. Cause of the issues is way too difficult to pin point exactly in my experience. I have tried BBS, and Wakelock detector. There was no way to see the cause, so I started playing the elimination game. Many apps I froze using Titanium Backup and checked the progress. Got very good result and I'm currently in the process of unfreezing stuff very slowly. Right now I'm testing Netflix and have a suspicion that there could be a bit of an issue there. If app is installed, it doesn't cause a problem, but when I cast a movie/show to chromecast, it maybe doesn't end session well. I noticed that sometimes I get a battery drain after watching. For now it is just a theory and stuff might get fixed with updates. My suggestion is to make a thread with "possible" broken/problematic apps that are suspected of causing issues, listing rom, kernel and observations. If enough reports are collected, it could be easy to avoid the issue and for developer to fix the problem. I'm not frequent enough on the forums to maintain such thread, but I think it would be very helpful if someone wants to do get it going starting with the most popular apps.

    I think that Doze is doing a piss poor job at keeping "bad" apps in line. Some apps are either not optimized correctly or have some incompatibilities that cause the drains. Function calls done through google play services prevent user from tracking down the offender. I remember in time of lollipop it was pretty easy to figure out what caused problems by looking at number of wakelocks from the apps and stoping it. Now it became too difficult to figure out using available tools/stats.

    If anyone is interested, my setup: SultanXDA Lineage OS 14.1 (June 7, 2017 - not the latest), sultan's kernel that comes with rom, Magisk 12 in core mode. No optimizations of any kind other than some frozen apps.

    Mostly used Web browser, Tapatalk, YouTube, digg reader. Also spotify, few minutes of calls on speakerphone, twitter Facebook, messenger.

    Achieved a new personal record - 9h 24m :victory: Light usage - mostly light gaming (card games, Atomas, Temple Run ...), some text messages, no WiFi, only GSM network, screen on auto brightness (slider at 30%) indoors, battery saver kicks in at 5% so it's basically negligible.
    Was using the phone until it died, then charged it while off and took screenshots right after it turned on.

    charge anytime it falls below 50% ?? what kind of logic is that and ? Do you have any facts/articles to support it or just making your theory?

    Absolutely. It's quite technical but by all means you should study up on battery tech.

    http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

    Similar to a mechanical device that wears out faster with heavy use, the depth of discharge (DoD) determines the cycle count of the battery. The smaller the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine. There is no memory and the battery does not need periodic full discharge cycles to prolong life. The exception may be a periodic calibration of the fuel gauge on a smart battery or intelligent device. (See BU-603: How to Calibrate a “Smart” Battery)

    Here is more:
    http://batteryuniversity.com/learn/article/bu_808c_what_the_user_can_do

    If you want to get extremely technical, you should NOT charge to 100% either. The optimal charge is between 50% and 80%. If you school/work right next to a plug and can charge, it's best to plug in for a bit when it reaches 50% and charge to no more than 85%. Unplug before 85%. If you keep your charging cycle like this, your battery will definitely outlast 90% of the user base out there. But it's not that practical. So my more practical advice is to charge when your phone battery to drops to 50% and let it charge to full. But if you want extreme battery life performance over the lifetime of your battery, disconnect from charger at 85% or less.

    Similar to an EV, Li-ion in satellites must also endure a lifespan of 8 years and more. To achieve this, the cells are charged to only 3.90V/cell and lower. An interesting discovery was made by NASA in that Li-ion dwelling above 4.10V/cell tend to decompose due to electrolyte oxidation on the cathode, while those charged to lower voltages lose capacity due to the SEI buildup on the anode.

    NASA reports that once Li-ion passes the 8 year mark after having delivered about 40,000 cycles in a satellite, cell deterioration caused by this phenomenon progresses quickly. Charging to 3.92V/cell appears to provide the best compromise in term of maximum longevity, but this reduces the capacity to only about 60 percent. (See BU-808: How to Prolong Lithium-based Batteries)

    The talk of % is really for lay-people. In the battery industry, it's all about the voltage. Charge your phone to 3.9V, not 4.2V or 4.3V for optimal long run battery life.

    Really happy with how doze kicks in. Device deep sleeps so well.
