Battery Charge Issue

This might have been answered somewhere, but i couldn't find.
My kaiser takes an hour atleast to get to 67% battery level on the power adaptor and as soon as it reaches that level it takes just 5 min to get to 100%. This is very strange. I performed a Radio upgrade to 1.70.19.09 a day before. But this is strange?
The battery status app starts with whopping +600mA of charging current on a 0% charge and drops to 100mA at 50% charged and to +53mA when it is around 67% and then in some time it says 100% with a charging current of +53mA.

Have you tried changing the radio back? To see if that affects anything?

Is your battery life normal? Does the same happen if you let the battery discharge once and charge it again? Changing the radio could have reset the battery meter calibration and it's just finding its way again.

Do you mean to say that i should give a few recharge cycles( a week may be) and this should be resolved?

Run the battery down completely once until the device turns off, that will also allow you to see if you have normal battery life, then recharge fully. Once is enough.

Doesnt work. I completely discharged my kaiser such that it switched off automatically. Recharged to 67% and then shortly 100%. i dont see 70-80-90% charges.

Once it switches off, remove the battery, wait 10 seconds, put it back in, turn on again. If the phone still says low batt and turns off again then your battery is really empty. If not the calibration is really off, run down again until it's really empty, then recharge without interruption until you get the green LED.
You didn't say if your battery life was normal.

same problem here
I have experienced the same issue. Battery is less than 60% and suddenly it reaches 100% (in a couple of minutes). My battery life seems actually very short to me but I must say I started using HSDPA the last week (my carrier finally offered it) and off course my battery lasts much less than before, so it could be just an impression. I flashed hyperdragon III Blackstone (nov 1st) last weekend and the radio is 1.65.24.36.
Just to give you an example, this morning I was listening to streaming radio over HSDPA and battery dropped from 100% to 40% in 50 minutes (screen was off all the time)
So I will try to empty my battery completely and charge it again. I´ll report after that.

Froyo battery % incorrect?

I let my phone run down to 16% and I was planning to let it go to 10% before plugging it in to charge.
At 16% I was on wifi and browsing websites when it just turned the screen off, made a warning sound and flashed the red battery light. After about 3 sec it started vibrating non stop which made me think of the 'discharge' feature on some phones, (which quickly uses/discharges the battery..), I didn't want it to go to 0% so I pressed (tapped not held) the power button which seemed to turn it off. I turned it back on, plugged in, and it booted up showing 0% batt.
My question is, has anyone come across this before? Should the batt % be this incorrect? and why did it vibrate..

My phone has been frequently below 15% without problems (yes, it's not very good for the battery, I know). It should vibrate once when it hits 15% and display the charge message, but that's it.
Happened once though that my battery discharged from 50% to 0 in literally 1 second, don't know what happened then, but it hasn't happened again.
Sounds like either your battery shorted or the calibration on battery % was way off on your phone. Try charging it to full and see what happens the next time you reach 16%, it might've fixed itself.

The other day my Nexus turned off at 11% :/

wipe battery stats after a full charge.. guess that will solve the problem

this isnt just a froyo issue, i am still on 2.1 and my battery dies at 8% EVERY time. it turns off, and when i turn it back on, it shows 0% but it died at 8%. its been this way the entire time i've owned the nexus. i'm not rooted so i never wiped the battery log files yet....but i will soon enough.

Ya my phone dies at 20% everytime. I just ordered a new one though

do that.
On 2.1 my N1, first my N1 had its multitouch laggy starting at 15%, then after some day of uses it shuts down at 1%.
Your battery just need to be calibrate.

Charging the battery with phone off makes it last longer?

Havent you noticed that when you charge the phone powered off it takes like 40 % more time for the batetry to charge but it also makes the battery last longer? is there any truth in this or im just crazy?

This is a very well know issue related to battery calibration. Take a look at the many calibration threads to learn about bump charging.
Basically, it takes longer with the phone off (or when you pull and put back the battery while charging) because in some cases android was stopping the charge before a full charge.
Try this
Charge your phone to 100% (inside android)
Turn you phone off
Reboot
Pull the battery before it boots
Wait for the ?
Put the battery back in and notice the %
If it says 60%, then you had 40% of your battery not being charge.
If you leave it in that spot and wait for it to go to 100%, your battery will be better calibrated.

and this hasnt been fixed even with gingerbread? yeah i have gotten the message saying it has 60 % :/

I pay no attention to the battery meter anymore. I've found that it just reads low. It's not that it doesn't get a fully charge, the phone can't read the level correctly. I tried draining the battery once by playing an episode of Top Gear with the screen on full brightness. The phone said the battery was at 5% but the video kept playing for another 1.5 hours.

noup , when my batetry says low , it dies pretty quickly

Go with mV.
4200mV=100%
3200mV=0%

[Q] Battery problem?

Hello,
I have an unlocked HTC One and I think I have some problems with the battery. For example, in the morning when I unplug it from charging and it's 100%, if I use it for like 5 minutes then the battery will drop by 6-7% and I don't think that's normal.
Then I was not at home today and I had like 19% and I decided to power it off. Then I turned it on after like 10 minutes, I had 7% left. I left it on for 10-15 minutes without using and it dropped to 2%. I turned it off again and then I turned it back on after like 5 minutes and it had 6%.
What is going on? Should I do a clean install of the software? I'm using ViperOne 6.2.1.
Thank you!

might be some app that is draining your battery, to confirm with gsam battery monitor. Maybe a rom/kernel issue or a bad battery....

Alright so I've done what the guy advised here http://forum.xda-developers.com/showthread.php?t=2765655
Apparently it fixed some of the problems but I still fail to understand this thing: so last night I had 73% battery left. I turned off the phone and then turned it back on after 5 minutes, I had 68% battery left. Why is this?
Also, sometimes the battery level shown while the phone is on does not coincide with the battery level shown in Recovery TWRP. Why is that and what can be done about it?
Thank you!

There is no way to know precisely what proportion of total charge is in a battery, it can only be estimated. Temperature, current drain, and many other factors affect the estimate. I think you're expecting too much.

battery dead or?

Well bought this phone back in mid 2017,and because of sickness I haven't used it that much at all.
I charged the battery 11 times so far and was keeping the phone in a desk drawer.
A month ago I noticed that the phone won't turn on,so I plug the charger on and charged the battery to 100 %.
I supposed that the phone was on,I didn't turn it off,and the battery left to 0% and shutdown the phone.
I really can't say how long it was on 0% (suppose like maybe a month).
Today I noticed very bad battery results.
Batterylife with GSam Battery Monitor is around 12 h only.
Was the "bolded text" the reason that battery died or the reason was not using the phone for 2 years?
Is there a software to check the damage of the battery?
I installed accubattery pro but for some reason doesn't offer me Health status of battery.

I would give the battery a few full cycles to see it that sorts it or yes, the battery it would seem is on its last legs. I don't know what app to recommend as an alternative though. (My battery is 23 months old and still performs as it did when I brought the phone)

I would drain it to 5% (maybe 1%) then charge it to 100% (without using phone while charging) a few times.
Then see how it goes. Afterwards charge phone from 20% or 15%.

Ok.I will charge it to 100% and report you with results with duration time on battery and you tell me how bad is it

GSam Monitor:
Battery Life: 3d 19.9h (5h 26m active)
Screen On:3h 40m (1h 17m Max)
In Android: battery estimated battery life: 2d 1h
