I haven't seen this anywhere else on these forums, so i figured i'd post this potentially useful info. Using the stock AC charger that comes with the inspire in conjunction with the Current Widget App, i have been recording the time it takes to charge the inspire over a variety of start conditions. I consider 100% full when current widget reports 0mA charging. I then took that data and plotted it with a corresponding trend line. There is of course a bit of variance due to any given percentage being associated with a range of current values, but the formula listed will give you a surprisingly precise ETA to charge your phone to full from any given start point. I hope this is somewhat useful.

FYI -
As you can see from the graph, there is a significant discontinuity from the zero point near 100% charge. This is due to the fact that i am using Current Widget to monitor when no more current is being delivered to the battery, coupled with a decreased current delivery from the Inspire 4G at higher battery percentages. This is a built in safety feature to slowly "top off" the battery near maximum to prevent damage to the battery from excess charge.
Basically, just because your phone says 100%, doesn't mean that it's completely, and totally, full of charge. The current widget shows the Inspire continue to charge (non-zero numbers) for about an HOUR after hitting 100%.
So if you simply want to see 99 or 100% in the display, subtract an hour from the charge time. IE, the formula would be TimeToCharge ~= -2.122*(current battery percent)+240.

Hi guys, I've flashed the 4.2.1 ROM by albinoman887 and only when the screen is on the lowest brightness it uses a lot of battery, really quickly.
Thread can be found here
When it's on standby the battery lasts for about 7 hours, but when it's on it lasts for around 45 minutes. Please help
I've tried
- Wiping battery stats
- Calibrating battery.

Your horrible cell signal is at least part of the problem. Your phone is constantly pinging the towers looking for a better connection. That's a serious battery hog.
You may have the wrong radio for your carrier. Or you may live in a dead zone for your carrier.
Also, is this your first battery cycle after a full wipe? I get results like that for the first discharge cycle after install. But then it becomes fantastic. Drain the battery all the way until the phone shuts off. Then charge it using a USB cord on your computer (not the standard power charger) for an hour past when it says 'full'. The slower USB charge can help to give it accurate voltage readings while charging so it doesn't stop charging too early. See if that helps.
The battery on Albino's 4.2.1 is pretty spectacular for most people, so the good news is that this is probably a fixable issue on your end.
The signal was when I'm out and about, most of the time I have 3-4 bars on HSDPA, I may do a full 24 hour charge or get a new battery
I have this problem too.But if i flash last build,baterry life is good.
See hidden screenshot below for system information.

Long story short, I've been noticing sudden system shutdowns recently at normal battery state of charge levels. Like ≈40% or even a little above 50%, for example. I have Battery Monitor Widget installed and I see battery current drain spikes just prior to each shutdown, like ≈2000mA or over 3000mA shots. This for sure is caused by some application, I use many at once but…
Mmm, the recorded voltage levels are pretty low, 3353mV or even 3082mA for the biggest drain shot. Now that I think of it and being the battery expert I am, this totally looks like an unhealthy battery problem, when charging the voltage also ramps up high and early. This means abnormally high connector and/or battery internal resistance. The terminal was bought second-hand and in superb condition, but now I guess that was due to the original owner having it inside a rubber cover case with a screen protector attached. Main problem nailed.
Carrying on with the abnormal battery power drain spikes, any of you noticed some application going rogue with power after some recent upgrade? Telegram maybe? Saw Telegram on top of the battery draining apps recently, and I do not honestly use it proportionally that much. Chrome browser usually is at the top but with a lower percentage to time ratio.
Buff! Did I fully answered myself?
Wellp, if some of you is willing to add something please do so.
2021/01/01 edit: The problem was indeed due to a weak battery, fixed it long ago.
Good morning guys.
Pls try this app and share your battery health status

I have my phone 11 months now and it shows 78%.
Yesterday I tried accubattery pro and it showed 85%
All this time I charged phone with slow 1amper charger and maybe 4-5 with warp charge.
Is it normal?
Thank you

Those things are not entirely accurate. For example blp699 that is the battery for this phone has 15.40wh that is 4000mah times average voltage of 3.85. But even these aren't entirely accurate, because the voltage rises as you charge the battery from let's say 3v or 3.3 to 4.4v.
When you charge the phone on a charger, the average voltage becomes 5v +- a few milivolts. So if you get the rated 15.4wh of the battery and you divide it by let's say 5 volts you get 3.08 Ah or 3080mah.
This math is done without involving heat disipation from the phone and charger, and whatever current is lost from the fact that maybe your device is powered on.
Use the oneplus diagnostic app. It shows the battery health like iphones.

It's the first screenshot. It shows me 78%..

I have Xiaomi 12s ultra, i was extremely happy with battery life.
One evening camera was recording while charging by mistake, when i wanted to check, it was 35>56 in 40 minutes, and phone battery charging was very slow because it was unbelievable hot. Did i just killed my battery?
I think battery is draining very fast after this. Can you share usage stats?
Is there any way to undo this, like draining battery to 0 and charging to 100?
Before this day i was using 20-80 charging method to save my battery. All efforts are gone i guess.

Yes, phone batteries don't like charging and draining at the same time. However, it could just as easily have burnt out or permanently deteriorate the quality of some electronic component.

Yeah i know. I hope camera sensor did not get any damage.
Yesterday i get about 5-6 hour screen on time, 14 hours without plugging with wireless internet only, %45 left. How much did my battery lost of its capacity with that incident? I guess my battery was better. Thanks for the chip in 12SU it didn't go on charging. It could have exploded.
I made a mistake to my battery.
I'd like to see what did i lose, can you share your battery usage screenshot.
What i did bad to my battery :
Charging while video recording by mistake, did i kill the battery?

Ask other users to post their battery usage screenshot remains very relative, indeed for absolute precision, it would be necessary that you use the same rom and especially with the same settings and that you use, for example, Chrome on the same duration, same for other apps.
Note that Wifi consumes more than data for certain uses.
Wi-fi Vs Mobile Data Battery Drain: Do Mobile Batteries Drain Faster On Mobile Data Than On Wi-fi?
Mobile data drains more battery than Wi-Fi because a continuous cellular connection needs to be maintained constantly with towers quite far away.

Seems like there is not a big problem. I'm sure it was bad in the first days. Xiaomi 12s ultra has a battery management chip, which is said to be repairing cells. It is doing what it says i think. Well done Xiaomi engineers. 5:30 SOT from morning to night with lte most of the day is simply amazing.
