NEXUS i9023 battery max at 93?

Hi,
anyone has the same problem as mine?
my battery max at 93. fully charged it will still display 93.
when ur batt is charging, it will display charging. but when it's full it will display charged.
yeah. my charged will display 93%. LOL?

I thinks its normal for the nexus s that it doesnt max out at 100%.
Mine usually is fully "charged" when its at 96% Battery.

i can confirm this, mine stops usually at 98%

Mine varies between 94 and 99, but most of the time it stops at 95.

From what I've heard, it's performance thing. Full discharges reduce li-ion life span, and 100% charges might also, to a lesser degree.
D720 is the same.

Yup mine gets to 95 and is done, I don't realty mind that but what I do mind is battery life I want it to last longer right now I barely make it a work day and I have to charged on my way home I'm tuning some services cause I need them just like I do in my iPhone but the battery dies too fast sometimes hopefully us cause I have for like 3 days

Normally mine stops charging at 95% but I've gotten to 100%.
Here's how I did it:
1) Charge the phone until it stops charging
2) Turn off the phone and continue to charge until the battery meter stops blinking
3) Turn on phone and enable "stay awake" while charging
4) Run an app that drains the battery (I used Angry Birds) and leave it on, don't turn off the screen
5) After about an hour it reached 100%

ps. It may be bad for the battery to constantly charge to 100%.

This is a known case to some Samsung devices, unfortunately
Thus, actually i would advice people to actually use it as it is, and dont let it bother you. after all, nexus s still have some pretty good battery life in general.

94% then as soon as I un-plug it drops to 89% but still lasts a day.

What's good for battery life? I have this device for over a week and I feel like it doesn't last the long, how much does it last you guys?

Download from the market ''Battery Calibration''. I almost forgot, i think u need a rooted phone because it deletes the battery.bin file.

samsung actually added this feature into the batt to protect it from overheat.
I think its weird and un-necessary anyway
but cos I have this phone i just need to live with it until I buy some new toy

Mine's roof is @ 95% :/

I have max on 97%

Q: I unplugged my phone, and my battery dropped from 100% to 95% immediately, or it won't/takes along time to charge past 99%, what gives?
This is by design. Your phone will slow down and eventually stop pulling charge at or slightly greater than ~95% regardless of what your battery indicator says. This is to extend the overall life of the battery, as constant 100% to 0% charge/discharge cycles will cause it to fail prematurely. If you're interested in really pushing it to 100%, you can use a technique that is called "bump charging" and is better detailed here: http://bit.ly/f6xiZ0

The answer is found in here. I suggest you look for the answer b4 posting the question next time.

[Q] 4 Hours charging time.

Anyone have this problem? Charging time takes 4 hours to 100%? It's really annoying. Charging time used to be only 2 hours (--and actually still only 2 hours to 100% if phone is off - ).

Mine is about 4hours from 20% to 100%. Sometime it take more than 4hours. I am on endymion 3.3. Is there something wrong?

Mine is CM7. Have you try switching your phone when charging? I get full charge in 2 hours when device is off.

2 h AC, 4 h USB charging time
Hi, I am new here but I think it will reset over time...
I have a DS with two different batteries (Stock 1450 mAh and Mugen 1800 mAh). I have noticed that charging them from USB takes about 4 hours and from AC about 2 hours.
I am using the Battery Monitor Widget Pro and soon the Mugen Power app to get the most out of the batteries.

2h 40min from 9% to 100% with phone off.
Sent from my HTC Desire S using xda premium

Check under about phone->status->battery status if it is charging with usb or AC.

FYI the stock 1450mAh battery charged from USB to 2-100 % in 4h38m in off-state (involuntary...: )
Will submit further info on new charging times as they occur.

My charging also lasts 4h since I switched to Endymion. Here is my charging graph, looks very awkward. 0-80% in 2h is OK, but 80-95 in 1h45 and then last 5% in 15mins looks bad.

Maybe you should check how much Amp your phone is charging between 80-95%. It could be that it is much lower than between 0-80%. I assume you use a genuine HTC charger?

I am having the same problem aswell, it just took forever to fully charge my phone now. I only just got this phone back in August, so I doubt it's the battery fault.
Would charging over AC be faster than charging over USB?

Yes, IMHO , charging over AC is definitely better & faster than USB !

Just tried it again and 100% is still 4 hours. I am charging AC.

I think its just rom related, but i can't confirm.
Sent from my HTC Desire S using xda premium

Battery Monitor Widget says that my average "AC full-charge" is 3h42min. With Reaper ROM.
I think it's not bad..
But would there be a difference with some other charger? Now I'm using HTC's charger.

i also have the same problem with you guys, but for months now
my phone used to charge 0->100% in 2 hours and now it takes up to 4.
i get the same graph from battery widget as above.
The strange thing is, when battery is at 80% (after 2hours charging) the mV value reaches highest because battery is really full. Try to restart phone and percentage will jump to 100%!
This happens with every custom rom
Anyway, battery has a 6 month guaranty (phone has 2 years) and now I know why

when i was on stock rom my phone took 2hrs to charge using AC. after rooting and romming a month ago it now takes 3-4hrs. i've had Coredroid as my rom for around a month and only noticed recently the long charge times using AC. battery monitor widget for me also says 3hr42m for full AC charge. i'm beginning to think its custom rom related as well.

[Q] tips on first charge anker 1900 battery

Hey all,
I just received my new Anker 1900mAh battery today and since there so much battery tips and tricks on the forums im confused about how to handle it when i put it in my phone for the first time.
Im a light user and on the stock battery with ARHD i sometimes get over 2 days on a full charged battery.
I just want that little bit extra that anker has to offer
My question is (since i see so much devided opinions) whats the best 1st charge time and what do i do to get the max out of my new battery ?
Do i need to reset battery stats in my phone before putting it in ?
Do i need to drain it first before giving it a full charge ?
How long do i need to charge it for the first (or first few times) ?
Do i need to drain the batt to 0% before recharging it ? or recharge it more often at eg 30%
Any imput on the subject is much appreciated.
Cheers in advance.
PS: ive added a pic of my stock battery usage, not to bad hey
I just want that little bit extra of the Anker and have a spare battery with me in case of emergency.

well there isnt much to it. what ive always done is just drain it till it turns off. then full charge overnight or ~8 hours. after that, you can charge it when it gets to around ~30%, letting it go lower wont do anything bad to it either. their supposed to prefer short frequent charges and to never let itself drain so low that its damaged. leaving it on the charger for long times will not damage it, their built to prevent overcharging. but battery stuff is very controversial. what i always do is drain until ~10% then charge it until its green for about half an hour. good luck. impressive battery results btw. im a moderate user and get ~2 days on anker, yours will probably last 2.5-3 days with that anker

Thanks for the answer m8.
I don't really do anything special to preserve battery, just have my brightness very low cuz the screen is the nr1 drainer and appart from that I turn WiFi and mobile internet on and off as I don't need them both at the same time.
Ill post back when i have the anker in use.
Cheers.

my method following partial guide in thread, but i couldn't locate it.
1. Charge till 0mAh displayed in currentWidget
2. reboot into recovery and wipe battery stat
3. boot into phone normally
4. Settings > Power > turn off fast-boot
5. let it drain till 0%
make sure you charge until 0mAh (or close to) in currentWidget, all the time
hope it helps =)

I got mine a few days ago and all I'm doing is following the instructions in the manual.
So after charging to 100% I let it drain to around 10% and then charge to 100% again.
Repeat another 4 times. I'm on the 3rd cycle.

Im on the 3rd cycle now as well, i just let my batt drain till 2-10% and full recharge.
Im getting between 2days-16hrs and almost 3 full days...
Lovin the Anker so far

Not to resurrect an old thread, but I just got this battery. It says on the battery not to use anything above 4.2v. I have 5v chargers. Am I going to destroy this battery by charging with more than the 4.2v in the warning?

Charging issue after OTA update to 5.02

I just took the OTA update to 5.02 last night, and now I am having issues with the battery charging. When I connect it, it starts out charging, then after a bout 30-60 seconds, it stops, and the splash screen for low battery appears. It cycles back and forth about every 30-60 seconds. After about 5 minutes, it actually seems to have lost charge. It went from 13% to 12%. I am using the charger and cable that was supplied when purchased. I also tried plugging a Note 2 charger into it, and it seems to be charging fine (obviously much slower than normal). This is what I am using now.
I never had any charging issues prior to last night. I am going to order a new cable, but am wondering if anyone else has seen this problem.

I had this issue also with the at&t model upgrading to the latest kitkat. I downgraded to fix it.

I think your problem is not related to the update. Battery charging problem could be from your cable or charger.
This tool will help you to find out the problem, charging current should be around 1.7 Amps, voltage should be around 5.2 Volts

I did monitor of battery discharge before update. The fourth column is battery percentage, I was playing movie and wanted to see how much the battery drops.
This is before update:

This is the discharge rate while playing movie after update to 5.0.2. It seems better
This is the charging rate after update. Battery charges normally without any issue

Battery issue after reboot

I'm having an issue with the battery level after a reboot that is fairly consistent and happens regardless of how much battery life I have left.
After a reboot the battery level will show a very low reading (anywhere from 1-10%) regardless of what the battery level was prior to the reboot. It's been as high as 98% before reboot.
If I plug it in to the charger again and immediately reboot, the battery will read a higher level again.
I've seen a battery not hold a charge, but am not sure that's it since plugging it back into a charger immediately increases the level by over 50%.
Anyone have any experience with this or know what the issue might be?

The battery could be starting to fail. You could try Accubattery or other similar app to check the health of your battery. Has the phone seen heavy usage (charge/discharge), and/or exposure to high temperature?

It was a display model so it's definitely seen heavy usage. I'll have to check out accubattery.
Here's a screenshot of how the remaining battery life wildly fluctuates.

That's the kind of thing that my Samsung Galaxy S3 used to do, until I replaced it with a Pixel about 6 weeks ago.
If you do replace the battery, I suggest using Battery Charge Limit to prevent charging above 60 or 70%.

I'm guessing you have the original battery which is 2 years old. I'd have it replaced.

Before I consider getting the battery replaced, anyone think this could be software related?
I did a factory reset already and the problem still persists, but I still find it weird that the battery level would go up after a restart.
Today, with limited use the battery seemed ok and slowly went from full charge to 54%. I took a picture and the phone shutdown. On restart it was 8%. I charged it up to 62% and then restarted to see if it would drop again. After the restart it said it was at 85%.
I understand a bad battery not holding a charge or discharging very rapidly, but not showing an increase in remaining battery life.

The whole concept of battery percentage is a fabrication to help us understand (and attempt to predict) how much longer a battery will last. Batteries have voltage and amperage. The amps are constant, but the voltage drops while the battery is being discharged. When a battery cell starts to fail, strange voltage fluctuations can take place. This confuses the algorithms which calculate battery percentage.
As a former display unit, your phone's battery likely stayed at 100% charge for months, including while being used. Keeping a rechargeable battery fuy charged for a long period of time is detrimental to its overall health.
Edit: Here is a great article on how to (and how not to) charge lithium-based batteries.
