Hi...can I use battery 1500mA for i9003?is this battery can damage my phone?
My i9003scl have battery cell 1650mAh. In your case probably have shorter battery life when using 1500mAh battery.
Yes you can use it

I bought new 1500mAh battery to replace my original which died becouse of being used so often.
So far it works good

do not forget to make 3-4 full circles of charging and discharging. And its better to charge device turned off

Last night before i went to bed my battery was 100% and when i woke up 8 hours later, it was at 13%. The phone was off!!!
Anyone else get this? IS there a way to calibrate the battery? That was its first charge btw.
It might just be because it's the first charge. "100%" probably wasn't actually 100%. Let it drain to 0%, then charge fully to 100% without interruption and hopefully you'll have normal battery life. If not, return the unit for a replacement.
Or wait until we have root/custom recovery, and reset the battery statistics in CWM. But good luck returning it if that doesn't work.
Most phones take a few charges and completely dead cycles to get the battery goin.

Just a heads up but resetting the battery stats in CWM dose not reset the information on the battery. It resets the stat information within android it's self about the battery.
There was a google engineer a while back that had a google plus write up on it.

Just to quote
This file [batterystats.bin] is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings. That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you. It has no impact on your battery life.

I wish people would stop saying to drain the battery to zero. This is not good for the long term life of the Li ion battery to do so. And there is also a small possibility that the phone and battery's safety circuit will not engage correctly, and the voltage will dip too low for the battery to take a charge. I've seen plenty of reports in the past of HTC Android phones (other OSes also) where XDA users drained their batteries to shutoff, and the battery was unable to take a charge.
Also, the battery meter is not remotely accurate enough for draining to zero to make a difference. Plenty good enough to drain to 10 or even 20%, charge to 100% (leave there for 30 min or so to ensure saturation charge), and repeat a couple times to calibrate the battery meter. No value added whatsoever to draining to zero. And the potential to shorten the battery life or render it unable to take a charge. So don't do it.

Another peeve of mine, you calibrate the battery meter on the phone, not the battery itself. The term is probably a holdover from the old NiCad batteries, where it would be typical to "condition the battery" by draining and charging to full in order to prevent memory effects. Again, this is not a good practice for Li ion batteries.

Or... the fact that you turned it off and on had something to do with it, on other Android phones, if I powered it off and on, there's a 1 in 15 chance that it drains almost all the battery...

I shut it down for the night like i always do with all my phones. Turned it on in the morning and bam, 13%.
Had it running from 8am till now and battery seems to be ok but i guess ill find out if it does it again when i turn it on tomorrow morning.
And whats wrong with turning a phone off then on? Doesnt make sense.

Good advice with one caveat. Occasional (like once every 30-40 cycles) full discharges are helpful to prevent a sort of 'memory' effect on the phones internal calibration routine. Over time, this can cause the phone to display remaining battery life incorrectly and actually run out of battery before it indicates it should.

Morning!
I was curious about battery age and such and pulling out my wife and I's tablets and took a peek with Battery Monitor.
I noticed one of them at 89% battery says 4148mV and the other at 99% battery says 4128mV.
Why would a lower battery charge have higher mV's? This may be an elementary question, but I always like learning.
Nada?
I did some googling but nothing definitive

ascertaining battery state of charge (SoC) is much more complicated than simply measuring voltage.
the amount of energy in a lithium rechargeable battery in particular is not a linear function of voltage at the top and bottom ~10% of the range, so the best way to ascertain SoC is to use a process called coulomb counting during charge/discharge to measure energy as it's transferred, which pretty much any respectable battery management chip or system employs...
---------- Post added at 11:34 PM ---------- Previous post was at 11:26 PM ----------
based on the health of one cell in particular versus another, the voltage at x% of maximum charge may vary slightly. the internal chemistry of the battery degrades over time, which makes it impossible to charge to 100% of its all-time maximum capacity, so a BMS must continually gauge the charge/discharge characteristics and figure out what the optimum min/max levels are, which means that what constitutes x% varies over time, also...
Just installed Dirty Unicorns (yesterday morning), love it so far. My one problem is it take forever to get to a full charge. It has been charging for over 10 hours and it is only at 87%. I had my phone turned off and when I plugged it in it was at ~0% battery life. Anyone know how what is causing it to take so long or a way to make it charge faster? The charger is the one that came with the phone.
I ran this command: cat /sys/class/power_supply/battery/batt_current_adc
The number I got was 0.
I got the command from this thread.
Edit:Tired it again after restarting my phone, I got 9078 which means it is fast charging. However, it still takes a long time to charge.

Check for battery deformities. If it looks swelled then your battery could be bad.
Sent from my SAMSUNG-SGH-I727 using xda app-developers app
The battery looks normal (no swelling, damage, etc). I tried charging it while it was turned on and it charged fine; from around 50% to 100% in less than 2.5 hrs (was watching TV so I am not sure the exact time). I am going to try killing the battery again and charging it with the phone on (than off) and see how long that takes.
So I don't have an exact time frame for it charging while off but it fully charged within under 8 hours (from dead). However, it still seems to charge much faster when the phone is awake; it took about 1.5hrs to get from ~50% to 100%. I am still confused as to why it charges faster when the phone is on. If anyone has any ideas I would be interested to hear them.
Hi, I just get my Nexus 5 yesterday and may I know how should I charge my phone properly to protect the battery lifespan? I am coming from a rooted Galaxy S5830 and I always discharged it to 0% before I recharged it. Should I do the same with my N5? Furthermore, may I know if the phone is charged, is it safe to left it on the charger for the whole day, will it hurts the battery?

charging technology has changed within these past few years. now a days you dont have to worry that youre charging wrong. just plug it in and charge it if needed. it doesnt matter if your phone has 89% left or is at 1%, charge it when its needed and dont worry.

Don't force yourself to discharge the phone to 0% like that, just charge it whenever it's needed.
With all batteries - don't overcharge
With lithium ion batteries - about battery dropping below 20%
I learned this when researching laptop batteries, so I assume the same applies for all lithium ion batteries.

I have an S2 plugged in 24/7 as an alarm clock. Lol
It still gets good battery life as always.
Special charging techniques and warnings are all wives tales these days.
Charge it when you feel like it and as long as you have to... Like over night. ?
i bump charge all day while im atcwork, and leave it on a charger for all night. same procedure as every single day this year, and still get wonderfull battery life on my phone.

you cant overcharge the battery. your phone will stop charging by itself, and not take in any more current until it needs it.
I charge it when it dies unless it's low and I need it the next. Morning
I bought OnePlus 7 pro 15 days back from Amazon
On installing accu battery app it's showing current battery capacity at 3687 mah.How can a 15 days old phone battery wear off so quickly like battery has degraded 10 % ?pls other's try and confirm

Accubattery isn't 100% an accurate reading only a estimate.
A battery's labeled capacity is more of a suggestion than an actual hard number. The most important number is hours between charges. Is that adequate for you?
The stuff some of y'all focus on. Assuming sot is high on the list also.
Of all the battery apps I've had, the only one that was accurate for me down to the minute was gsam rooted
Sent from my OnePlus7Pro using XDA Labs
In addition to the app not necessarily being accurate (I don't use them), it is fully possible the battery is less than the stated mAh rating. It was years ago (but battery technology really hasn't changed much for these devices) there was a thread by an xda member that did testing on a number of OEM and 3rd party batteries. Hardly any met the rated mAh. From what I can recall, maybe 20% met or exceeded the rated mAh.

Fully agree here. I have no issues getting through a day on a charge. Although my usage is not as heavy as other folks. But I am quite satisfied with the battery life on this device, idle drain, etc.
How many charge cycles have you gone through since starting Accu?
For 15 days will be reasonably accurate, but if you've only had 1 or 2 charges then Accu will be much less accurate. Also, do big charge sessions , e.g. 20% to 100%, and leave the charger connected for a while after hitting 100%. Lots of small incremental charges won't help accuracy.
