Bluetooth battery drain - Lenovo P2 Questions & Answers

Before flashing a custom rom i had no problems with my p2 at all. Last week I installed the lineage 14.1 rom and now suddenly the bluetooth function drains my battery a crazy amount. It can go up to 88% of the total battery usage, i think on the stock rom it was about 5 or 10%. I searched everywhere but couldn't find a fix for me. Any help?

Sometimes it is a bug n shows wrong statistics

I don't know the sot exactly. But it has been a big difference since then. I used to charge my phone every 3 days and now i have to charge it almost every day. It has become a pretty big inconvenience for me

Jelly Bean Draining Battery

Hey,
I recently unlocked my bootloader, rooted, and installed CM10 on my HOX. I did a full battery drain and then full recharge before using, and still noticed that my batter is still being drained at a worrying rate. (3 hours gone and just 57% battery left) The screen takes 52%, but the Android OS takes 21% and the Android System takes 5%
Is there anyway I can reduce this battery drain? I understand the ROM is still in Alpha, but I've heard people still achieving 3 hours screen time with it! Maybe something to do with getting a new efficient kernel ? (I'm still new to all this).
Many thanks in advance

Firstly, what kernel are you using?
Give it a few days to settle in first.

Stock kernel I presume :/
Try another kernel after a few days of letting things settle in.

hi there - just a thought of sharing with you since you've already rooted your phone -
- Domination ROM CM10 thanks to Owain94 check it out on the forum http://forum.xda-developers.com/showthread.php?t=1799375
- NCX 0.99bOC kernel by n3ocort3x see comparison here done by nimrodity (thank you guys) http://androidroots.com/king-of-kernels-kernel-comparison-htc-one-x/
Again it's a custom ROM expect for some bugs to come up - but you decide at the end since this version are better than alpha
Enjoying the flexibility & efficiency of the battery life on my HTC One X!

Oneplus 3 Nougat Battery Life

Hi all,
Now, I've never gotten great battery life (combination of screen on time and idle) with any phone. I don't use them all that much apart from bursts and my OnePlus 3 would get me 3 hours SoT tops within 24 hours before I need to charge again.
However since Nougat I'm struggling to get even 1 hour SoT.
I'm using Bluetooth, NFC, both SIMS and nothing else untoward. This is the same as pre-Nougat.
Anyone else seen their battery life die since the update
Try to use 1 sim. I have 3:30 sot for both sims. And 7 for 1 sim.

that's still more than 3 times what I'm getting for 2 sims...
Did you clean flash or dirty?
Rooted? If yes, which supersu version?

Batter life is great i suggest you do a clean install wipe everything on your phone after making a backup on your phone ofcourse and start again. I use 2 sims and i have an average of 5:30 to 6 hours sot

Hey Konvict
Can you answer these questions then please?
How long a period of time is that 5-6 hours of SoT over? 24 hours of standby?
What radios and apps do you have running that might eat battery?

I would say about 24 hours....i normally charge my phone at the end of the day when i have about 40-55 percent battery left but even then i usually have goften 2:30- 3 hrs screen on time depending on the day. I will attach a screenshot of my battery today and maybe u can take a look at it.
Actually today this nougat looks very good.
I'm getting awesome batter life.
First two pics from OOS 4.0
Last two pics from OOS 4.0.1
You both seem to be using both WiFi and multiple SIMs - strange then.
I can't use GSAM as I don't have root and Nougat stops the app by app recording of battery use for third parties, otherwise I could see what was happening.
I do have a number of email accounts, and messenger apps, but these sit dormant most of the day (i have no friends obviously lol)
Hmm, maybe a wipe IS needed.
You guys got a great battery life, I got 2:30 in my good days, never above it!
However, someone told me to switch Doze off from developer options, I just did that and I'm currently charging my device, will see if it do any good by the end of today "fingers crossed"
PS. I'm using Freedom OS 2.0 with clean install + using Bluetooth and 2 SIM (one for calls and the other for data)
I'm also noticing a big drop in battery life after switching from marshmallow to nougat on my OP3T. Cleared cache & did factory reset, as I always do. All apps and settings the same, and usage the same. Drain seems to be extreme, not sure what's going on. The battery life was AMAZING on marshmallow... kind of regretting switching now

Go back to the previous versions of Facebook and Messenger. These two have been draining battery like hell for sometime now.

One plus 3 best rom for Screen on time

Can anyone tell me that which is the best rom for screen on time.i am using stock rom.just me a rom that can give a 5+ hour screen on time...i have posted my usage in screenshot
OOS 4.0.2 with OB7 firmware. Then flash render EAS kernal. EAS will make sure that you get the most battery out of your phone.
It doesnt fully depend on the ROM. If u really want good battery life then its all about tweaking. For example flash LOS14.1 with bluspark/ElementalX/Franco then apply a AKT profile, for further explanation of this head to the advanced kernel tweaking thread and then download the akt APK. Then choose which profile u think suits the best. U can choose from battery/balanced/performance. Then u can easily reach 5h SOT. Hope i helped you.
I have 8-9h SOT on sultan's CM13
Screenshots: https://forum.xda-developers.com/showpost.php?p=70828408&postcount=668
Beta 11 with Franco's kernel. 4+ guaranteed SOT for me with a moderate gaming ( CoC and CR .... Both battery hogger )
Plus both Sims and 4g data on one is on mostly.
If you want more battery then you should try AKT ZHANA but for me it made my phone slow. So avoiding it at this moment.
Hope it helps. Thanks!
SOT is personal and doesn't mean a lot you can leave your display on with sync off, 0 Brightness and get 20hrs...
Try different setups maybe ditch some apps and log in with optimized sd browser etc
I have got my best SOT with Slimroms
It really depends on usage more than anything else. For example, I'm consistently getting 5-6h SOT on stock ROM and kernel, no doze tweaks or anything. Never got below 4h, once hit over 9h.

my constant is with 4 hours sot with stock 3.2.8. could be better with 4.0.2 or whatever.. but i stopped thinking about the sot coz its just making me paranoid everytime i look at the battery stats. as long as the phone can hold up till end of the day then im good and as long as i can get off a charger everytime im on low battery then im damn fine

I agree with this as well. I think back to my note 4, and just wanted a better that would last until I got home.. I frequently had to plug it up or swap batteries halfway through the day.
Now with heavier use, [and more knowledge of android] regardless of what I do, my oneplus 3 always makes it through the entire work and school day.
H2OS Beta 7, stock kernel + root +greenify +juice defender(default settings). It's the best battery duration I have with OP3. 5-7h sot generally.

They are talking about unplugged screen time ... I see no other way you could get 12 hours sot from this phone. I'm not calling you a liar just saying I don't think it's possible.

Everything works fine except for battery life.Some people using RR6 are having a excellent battery life.There must be something I can do to improve the situation.

Broken? Arasthel's LOS 15.1 is running very smoothly for me with decent battery life, not much worse than MIUI for me.
I'm running RR 6.0 now, never have that kind of battery drain.

Half of the calls had no audio for me wit LOS 15.1. I definitely did not do anything wrong, I did your flashing sequence with total wipe. It was also draining battery and getting hot. I have no clue how it can work for some people and not for the others.

Maybe you should properly calibrate battery once new rom is installed. That helped me before.

I don't have a battery screenshot right now. But I definitely don't notice much drain when the phone is idle. I get 3-4h SoT per day with 20-30 percent left. I use bluetooth in the car a lot and always have it on, almost always on wifi. Don't notice any drainage when on LTE though.

I found out where the cause is.It's the location setting.Default location setting is high accuracy,which costs a lot of battery life.I turned it off and it's all fine now.9 hours idle,4 hours SOT,40% battery left.Really satisfied with that.

I really dont know the reason. But one thing is that because I came from MIUI, after flashing the RR, i do the "format user data" just to make sure everything is clean for a different kind of Rom. It would be a bit hassle to copy things back to the phone, but I just have to do that format thing once.
Also I use greenify with aggressive doze. That's it

I have no audio on calls - again. This is really starting to piss me off. If no one else has this, then it must be a problem with my phone. I have never tested it with miui to be honest, I flashed custom roms right away. I guess now I need to go back to stock to see if the issue persists.

It helped me. I am not getting any drains. Give it a try you got nothing to lose. Just discharge your phone fully and then leave it turned off to fully charge.

Question Miui 14.0.4 stock Battery drain

Hello
I recivied 3 days ago a new update to Miui 14, before update the battery work for 24 hours good (40-50%), now afrer 12 i'ts 20%.
does anyone have this problem?
I am using Miui 14 (xiaomi.eu stable edition), and I also experience battery drainage. I am looking for any updates, but they seem to have dropped their weekly updates for Lisa (the 5G NE). Let's see now, because I ended up liking Miui and not like the UI of any other roms...
yes have the aforementioned problem of battery drain. Since I kept this phone as stock I cannot even revert version
Yes, I've faced the same problem. I was getting 10% overnight battery drain. Then I flashed custom rom(AOSP), and now the overnight battery drain is 4%. MIUI su*ks

On my Mi11 used to get 2-4% battery drain overnight on MiUI13, since i updated to MiUI14 i get 8-14% battery drain, counting i usually sleep 7-5 hours, it's not an issue since i can change fast, but it's goddam annoying that now i consume 15% insted of 10% per Youtube watching hour
One thing could be done is unintall Carrier Services updates.
Any custom rom > stock miui
I've noticed that "com.android.bluetooth" is draining battery. Is there some fix?
