look another battery life thread...oh wait its a good thing.

Here's a situation two ways of charging the phone 2 results.
1.Battery gets low TURN OFF the phone and charge it
2 battery gets low charge it while ON..
Two amazing results
1.charging the phone while off still yielded a full charge of 4200mah
2charging the phone while on yielded the same 4200.
Nothing amazing right? For the past 6 days I've tested this from a stock cm7 ZERO 3rd party modifications same activities for the last 6 days. 6 hours standby and 1:30 minutes of usage in browsing 4g only never wifi for usage. Now results
charging while off -20% really really dissapointing...
Charging while on - 50% BIG BIG diffrence. I've never touched any settings I just accidentally noticed that I left my phone on through a charge overnight and amazingly best battery life I've ever had on the atrix.

Why is there standby drain (Android awake) after replacing battery

Whenever I change the original battery of my Redmi 1s with a Nohon replacement one, with same settings the standby drain goes from 1% every 3hr to 1.5% every 1 hour, thats over 4 times worse standby performance. Looking at battery stats when the Nohon battery is in, the phone is kept awake alot by Android (around 1hr for every 4hr standby). However the battery performs better in actual usage, if I play a game for 30minutes the Nohon loses a bit less percentage. I can replicate the problem over and over again whenever I change the battery back to 3 year old original, stanby drain stops and awake time by Android stops rising.
Its supposed to be one of the best brands for replacement batteries so why is it causing this standby drain issue, is this normal when you change a battery on any android phone and do most people just not notice it?

bump, is it worth buying another replacement battery or is this something that normally happens with replacement batteries?

1080p vs 1440p battery life

Hey guys i know there are many forums that discuss this but do you really see a difference in battery life between the two? (60hz both) for me the battery life is the same...
I left mine on 1440p 90Hz since day one and I have never depleted the battery on my day to day use. Usually by the end of the day I have anywhere between 50% to 30% left before I plug it in to charge.
Battery life is great using 60 or 90 but mines set to auto using auto90 app. I use fhd to. I lose 7.63 percent a hour screen on currently.
Would say mines also on 7% per hour...
With Samsung Internet darkmode battery life is insane..

Question Realme GT battery life

I'm not really satisfied with battery life of my less than two months old Realme GT 12/256 GB.
What is your average screen on time on this phone?
Mine would be in the 3.5-5 hours range in a day and a half, maybe more if I watch a movie or something.
I'm not playing games and only have Viber, WhatsApp, Facebook... usual stuff.
I didn't see any tanglible difference between "auto" and 60 Hz screen mode regarding battery life.
Also, what percentage of battery drain do you see overnight?
I'm on latest firmware, tried every possible battery saving combination, but always have at least 3% battery drain overnight (usually around 4% in 7-8 hours) and that with radio and all apps off and various battery saving settings applied (global and per app).
I'm starting to believe it's "normal" for this phone and its SD 888 chipset.
Thanks.
Same
I have very similar results as you. Battery life is just ok.
Current battery life:
from 93% to 28% in 1d 19h, SOT: 3h 15min.
Before this I had Poco F3 for a month or so and I don't recall exactly, but it was something like a 1%, 2% max. drain overnight with pretty much the same usage pattern.
Also I have Lenovo tablet with far weaker MTK CPU but not much bigger battery (5000 mAh and 10.3'' screen) and that one almost doesn't use battery in standby mode (beats all phones I had).
I'm currently disabling various apps and testing and I'll post here if I find out something useful.
Optimized standby - Ultra standby makes exactly no difference in my current setup so I turned it off completely.
Quick device connect is also turned off and not in use, as far as I can tell.

Question Wonder issue

Hi guys , I have bought this phone for about a week, the problem is that when the battery percentage is 14 to 11, it drains within 30 seconds and then the consumption is normal, I sent it to the dealer for that. They installed the latest version of miui. This was useless and the problem is still there, does anyone have this problem? Or if there is a solution for it, I also did the calibration.
I dont really understand what you are saying, i usually charge my phone whenever it is at 20% or something but there have been instances where it dropped to 5% too but I never noticed it specifically from 14 to 11
I have been using it for about a year now, so far things are good at my end and in general i am satisfied with battery life and charging speeds.
If your phone charges up fast, and overall battery performance is good with 5-6 hours SOT until you reach 20% i think it's good
I have the exact same issue on my Poco X3 GT. When the battery reaches 14% it drops very fast to 11% and then everything goes normal again.
