Hello guys, I have a problem with the battery, it all started about two weeks ago, I did 7h of screen per day, unfortunately one day my Redmi Note 7 Lavender (with PE +) had a drop in battery performance, from 7h which I was doing now I barely do 3, I tried reset, rom change, battery calibration, kernel change but nothing, I also tried to go back to the original firmware but nothing, do you think it's a battery problem? why doesn't it seem right that I have to change the battery now, it doesn't even have a year of life, if someone has found this "battery drain" could you help me?
Same here

I am getting the same issue on LineageOS. I was getting about 7h + of sot but it dropped down to 4h.
Waiting for an update that might fix this issue.

Its not about ur battery problem.
I suggest dont use gapps rom like Pe+, evolution x,etc
Rather use minimal roms for bb and daily driver like Lineage os by erfan Official,aicp,revenge os(11hours screen on time) ,bliss (8-9hours screen on time) ,aospa, etc
If u want more information pm me on telegram @fardeenansari

Hello everyone, i am writing this thread today, in hope of getting some battery tips from you lot, why? Well because my phone is having some serious battery issues, it only lasts 6 hours max, no matter which rom is on it, which is just not good enough.
I have used the stock froyo rom, SlashDW's CM 7.0.1 unofficial rom, and now running Frosense, by Rushness, but i have had no sucess with this battery problem.
Hopefully someone can help me solve this issue, i would be very greatful, thanks.
Try to wipe battery settings from recovery before flashing rom.
like extrahacker said, wipe battery stats... than leave device powered off and charge till full, than re-install rom of choice
I looked at a post regarding that on the web, and followed the instructions. Charged till full, wiped battery stats, and then let it drain and charge again, still no luck. Any other ideas? Thanks for your help, you both
I find that the CM roms are very battery consuming. The Froyo for Trout rom gives me a full day.
You must also consider that the battery is 2+ years old, it would have high battery wear. Which might explain why you have bad battery life.
Agree with Ace42 - I recently acquired a G1 and the battery life was shocking, I was lucky if I got 4 hours! I have just switched on my phone with a new battery from ecell off ebay and will give it a blast over the weekend.
It can't do any worse but I am hoping for at least 8/9 hours!
OK so the first day I just scraped 24 hours... it must have been the old battery!
I can't complain!

Hey guys i got a s4 for free a few weeks ago and the battery was having issues so i brought a new battery from Samsung for $50. I guess the phone is $50 now huh, still that's a good price. Anyway i have an improvement in standby time over the old battery that seemed to drain no matter what, but i only get around 2hrs to 3hrs screen on time full brightness with a mix of auto. The phone tends to get warm when its below 40% power. Also using the phone drains it at a fast rate, but standby only 1% per 8mins or so witch is good. Im backing up with twrp and titanium backup, ive tried recalibration, and im about to do a factory reset on this (stock touchwiz)

Battery calibration apps are a placebo.
Anyway, let me tell you a little story:
2 weeks ago I watched a 2 hour movie on my phone. Started from 100% ans towards the end of the movie I was left with about 50% battery.
Screen brightness was around 60%, WiFi was enabled and the mobile reception was 4G.
All things considered I would assume I can get 4 hours SOT, since it took 2 hours to get from 100 to 50.
This is on a custom rom and battery oriented kernel settings.
Also take into account that I was watching a movie, so the CPU was idling most of the time. Doing tasks and switching from one app to another drives the CPU up.
Your screen-on time seems acceptable to me. I have to mention that my battery is one and a half years old, but I always took good care of it (I never let it discharge too much and never left it charge too much, as both of those, over time, can reduce its storage capacity).
Im using Albe95 rom with a custom kernal and the battery is draining slightly less, ive reduced my brightness to 60% and its drained from 100% to 77% in standby and extremely light use in 6hrs (about 4hrs standby drained 6% and 2 hrs of on off use every now and then drained about 17%. I guess im used to my old LG L70 D320n witch could hold up at full brightness forever. Will Cyanogenmod 13 bring much improvement for me?

I don't know. Maybe Optimized CM13 because it has a custom kernel and you can select battery or performance profiles.

You won't miraculously get 5-6 hours SOT even if the battery is new.
Maybe with lowest brightness, WiFi and mobile data off you will.
Underclocking and undevolting might help a little, but I don't see anyway of getting more than 5 hours.

There's a guide in the general section, _Bon_Bon's tweaks.., Something along those lines is the title.
It has a guide on how to increase battery life.
The guide is based on alucard kernel, though.
Alucard kernel is available for any 5.0 and 5.1 roms. But there is no public build for android 6.
Only JDCTeam roms have alucard kernel for android 6. Those roms are Optimized CM13 and AOSP 6.0 rom.

Ok so slowly things have improved but today when it was at 9% (6:30pm charged this morning) it froze up and i pulled the battery. Then it jumped down to 2% at restart! This has happened before (cant remember if it was on stock rom or the note 5 rom im using on it now) from 40% freeze, pull battery, restart, 22%! Any idea why this happens. I talked to samsung about the battery performance and they just wanted me to send the phone too as "its not just the battery" just for more money instead of honering their 3 month ****ty warranty! Stick it samsung my next phone will be lg like the rest, even though i only just brought this damn phone

The freezes might be caused by CPU undervolting, if you did any.
But the battery percentage dropping suddenly is a sign of a bad battery. It might drop 2 or 3% during the boot up, but not 20%.

Samsung say the phone is the problem. Today i got to 40% and it jumped to 30% within 20 mins. Then i pulled the battery and started the phone up, repeating this multiple times to see the battery percentage. It jumped between 24% 15% and 19% up and down each time i pulled battery and restarted (no crashing just to see what happens). Is this enough to tell Samsung ITS NOT MY PHONE.

Apparently they refuse to accept the possibility that they might have sold you a faulty battery, so they blame the phone.
I don't see how the phone might drain the battery from a hardware perspective.
It's possible from a software perspective, but since you changed roms it is unlikely to be software related.
Did you install any apps to check if the phone enters deep sleep? Or if there is anything keeping the CPU at max frequency?

How did you calibrate it?
Battery calibration apps are a placebo. What they do is they delete the batterystats.bin file which, as stated by a Google engineer, has no relation to battery life or the battery display.
Also, that file gets deleted automatically at every reboot by android itself.
What you could do is:
First let your battery fully discharge, until the phone turns off. Then try to turn it back on. If it turns on, proceed to use it until it turns off again. Do this until the phone won't turn on again.
Now the battery is completely empty and you can plug it in to charge. Let it charge to 100% without interruptions.
Take into account that it can take up to 3 hours to fully charge.

Haha done this before to no avail. Will do again but i noticed battery life is generally better if i leave it charging for 10hours after its charged fully. Instead of taking it off when it gets to 100% but i think a long worded and very angry email is about to be sent to the Samsung repair centre
Sent from my LG-D320n using Tapatalk
on my travels around google I've read many times that with lithium batteries you NEVER want to completely discharge or overcharge them. give it 10 minutes extra once fully charged, not more. you're damaging the poles or terminals or something I can't remember fully when at either extreme. all you achieve is a shorter lifespan for your battery.
discharge it until it turns off but never until it can't turn on again. it has a chip in the battery that needs to stay powered too.
Hey guys, How you all doing ?
First of all, I recently got in hands a Nexus 6p! Bought It used (8 months of use), and its perfect, everything os ok.
Then, I rooted It and now i'm using the Android O ROM, with franco kernel.
But, I've been noticed that the battery sometimes drains 2%-3% too quickly. And yesterday my phone shutdown at 18%!
I was experiencing the 2-3% drain on 7.1.2, but not the shutdown.
I dont get that bad SOT, like 3h-4:30 is still a thing for me.
What do you guys think ? Is It bad battery or software related problem ?
Should I consider doing this trick and go back to Android N ? https://www.google.com.br/amp/s/for...-6p/help/nougat-battery-bug-fix-t3559250/amp/
Here is one print from my screen on time and accubattery.

First of all, going "back" to anything is not going to help you. Android 8.0 is not the issue, it may be a degraded battery, especially if you are having early shutdowns. Please open the Health page (Saúde) and post it. That is where you will find your estimated battery capacity relative to a new battery. You should have a few full charges before this percentage stabilizes. Try draining it as low as you can go (or when it shuts off), and then let the phone charge fully until Accubattery tells you your phone is fully charged NOT the phone reporting 100%. It's common for the phone to continue charging 45-60 minutes beyond the phone reporting 100% and you need to keep it on the charger until completely full to get an accurate capacity estimate. Hope this helps. Boa sorte!
Okay. I went back to 7.1.2, early shutdowns got resolved, but the 2℅ drain not.
I followed all the steps of the guide I posted, changed governator, etc..
It have seen to got a little better. Will report back after a few days of usage with accubattery health status.
Thanks!
VS995, Rooted, been running WETA since last January.

About 2 months ago I noticed whenever my phone got to 15% battery left when I plugged it in it would reboot. I ignored the issue for a while because I rarely let it get that low.
Recently though I notice my battery life getting very bad. Insanely bad. Not even 2 hours of SOT, dying in 3 hours just using hotspot with no SOT. Losing 10% in a few minutes of active use sometimes.
So I tried some battery calibration apps, tried recharging to 100% and draining again. Tried wiping battery stats. Tried different ROMS.
I flashed desolation ROM tonight and the battery life seems to be really good on it but it ended up shutting off at 24% left.
Battery apps say my battery is in good health, but I'm wondering if the battery itself is bad? Any tips or advice or help of any kind is appreciated. Thanks

I just wanted to make sure because I've never experienced this issue before. I even hand my smartphones down to my mother and they tend to get over 2 years of use and I've never had to buy new batteries. Thanks for the feedback
If it drops from 24% to 0 then im pretty sure its a damaged battery try it ypu can buy it for less than 20 dollars on ebay
If it drops gradually in standby you could have also a battery drain bug but this is not the case here
Hi, I didn't find a Q/A thread so I ask here.
I came from a rn4. I loved to use Los ext, it was one of the best rom for battery life. Now I am with miui 11 stock and debloated (I removed almost all ****), but still I m having a battery drain. In fact tonight it used 5% of battery in less than 8 hours with wifi and screen rotation only. I think it's too much!!
I red that some people can last their android battery up to 3 days with 4 hours sot, and I was stupified.
So which is the best rom at the moment for rn7, looking at: stability, smoothness, battery life, gaming, customization?
Does Mi app like themes, fonts, etc are removed normally in roms, and if yes, do developer create their own menu in setting for these things?
Who is using the Rom that will suggest me, which SOT you get and how much battery drain do you have in 8hours sleeping time with wifi only?
Thank you a lot! ?
When system running ok i got always the same sot on each rom i tested.
Stock Global, xiaomi.eu 10 and 11, pixelex 9+ and LOS16.
in each rom i mostly get 2 days with 6-7 h SOT.
battery drain over night in flight mode only 1-2%.
no big differences in the Roms for me.

That is still way too much for such a big battery ESPECIALLY in Airplane mode. It should NOT drain a single % of battery during more than 12h of idle, where as right now it can hit up to 10% for me, which is just unacceptable
For me, my phone doesn't lose any single percent of battery in 12h, in airplane mode

There are actually massive differences... IMHO one of the best ROM's is not even on XDA. https://os.revtechs.me
after a new install of LOS 16......
last 2 nights in airplane mode i didnt lost any percent.
first complete akku charce i got easyly 8h+ SOT
maybe old install was faulty....

HI, are you using some of them? How much sot?
It seems that rooting and using Roms on this phone is pretty useless on the battery side, because nobody talks about 9-11 hours of sot using roms.

Rooting is absolutely no problem and who ever presumes having 9-11 SOT is simply hallucinating... 7-8h is realistic... I don't even want to imagine how sad individual lives are being staring at a phone 8h out of a 24h day...
