Greetings all, I was wondering if anyone else has noticed that their battery doesn't charge to full when using the wall charger or USB? I have LiPo chargers from RC cars and I have used one to discharge and fully charge the battery to 1400mah and found that the phone seems to have much better battery life than when charged with wall charger / USB.
When charged with the external ("direct") battery charger, I can get to 4211mv whereas normally with the wall/usb it only goes to 4173mv max. From what I know of LiPo/LiIon batteries, they need to get to their max charge voltage (~4200mv) or so and stay there for some time to get full charge.
I have noticed that my phone has terrible battery life when compared to my Touch HD which used to get 20hrs+ of full use on 3G/HSDPA, same usage pattern with push e-mail and I can't even get 12hrs with the Nexus One before the battery runs right down. And I thought the Touch HD had bad battery life!
Any help / feedback would be most appreciated. Thanks!
It's interesting I see this as today has been a very odd battery day. I woke up and unplugged it at exactly 5am. For 7 minutes I checked e-mails and twitter and it had dropped 3%!!! By 8am I was down to 82% (ride in to work, listening to music for 25 mins, thats about all) I was thinking this was getting silly. It's now 5pm here and I'm still at 61%?!?! So, over the first 3 hours it went 6%ph, since then it's done 2.3%... that's the best I've ever got from it.
Could this be related? It's not really fully charged, even though it shows 100%, drops very quickly and then when it returns to where it perhaps should be (around 80%) it acts as normal?
What is a LiPo charger and how can I use one to charge my Nexus battery?

iMAX B6 is what I have been using. I have another heavier duty one but this one is good enough for the battery. I have a generic battery charger thing which I got from China which holds the battery while the other unit charges it. Right now as I write this, my phone has been on for 1hr 25minutes after being charged with the charger, I have used the browser for 10minutes, on 3G, downloading things etc. and it is still on 4211mv and 100% charge.
Curious if this is an issue with the onboard battery microchip, or the radio/firmware. Does anyone know where to source an original replacement battery (non-generic replacement)?
The batteries in these smart phones makes no sense. The other day, I charged the phone overnight using USB, and the next day, I was at 97% after 3.5 hrs. Then, another day, with basically the same usage, I'm down to 85% after 3.5 hrs. No rhyme or reason. I wish someone could explain it.
I also wish someone could make a battery that lasts for 48 hours on normal use
"Drops very quicky"
same here but ive had this 'problems' since stock firmware. its not CM related.
I also noticed that its dropping from 100 to 80ish very fast when starting many apps in the morning for example. Like stopping airplane mode, starting some apps and opening browser. stays at 80ish for some hours then

Yep. That was the same thing with my Pre. It would never stay at 100% for more than a few minutes, and then it would plummet into the 80's, and then it would be okay.
Battery Antics
I purposely left the phone not to charge last night from about 1AM - and I woke up (around 9:30AM) with it at 99% charge still. Used it for a bit and it dropped to 89% and now it's 1:06PM and it dropped to 75% with calls, web browsing and some other stuff. Previous days to this it would be at 75% after just 2-3 hours!
I also noticed that the phone didn't download any e-mails overnight (since there's no "scheduling" for peak/offpeak like in WM I assumed this shouldn't happen?) which may account for the minimal discharge.
All in all very strange, seems like I am not the only one with these problems - maybe I'll try get another battery and see what happens!
The thing about the battery in a smart phone is that it has a micro chip in it, and the phone reads info from it to give us the battery meter(this is true of any phone, actually)... your LiPo charger reads charge in a similar manner, only it doesn't talk with the batteries chip, instead it does it's own thing(I will spare the details)
With this in mind, what you want to do to get the most out of your battery is get the chip in the battery, and in turn the "circuit" it completes with the phone properly calibrated. To do this, you want to run the phone's battery down until it turns itself off. Do a battery pull and let it sit for a little bit (at least 30 seconds, I usually wait several minutes)... then, put the battery back in, and turn the phone on. One of two things will happen, it will either power off before fully booting, or if it does not you will want to use the phone until it powers off again.
At this point, pull the battery again and let it sit out of the phone for a bit again. Then put it back in, and without trying to power the phone on, put it on the charger and leave it on the charger until it is fully charged "green light comes on" plus a couple hours.(best to leave it on the charger overnight) At this point, take it off the charger, and then turn the phone.
This will properly set the low point and the high point for the battery stats. Do not do this a lot, it is bad for a LiIon battery to be "deep cycled", which this comes really close to doing. Ultimately, the phone is not going to charge the battery as high as a LiPo charger will, nor will it discharge it as low, because unlike an RC car's batteries that are used for rapid discharge, these batteries are designed and used in a slow long term discharge.
Thanks, I'll try that myself
Do you run any risk of damaging the battery when charging with a LiPo?
How to Make Your Cell Phone Battery Last Longer when you need it the most
Tips: How to Make Your Cell Phone Battery Last Longer when you need it the most:
1. Always try to drain your battery or wait till its 15% or below then charge your phone. Its very important to turn the phone off before you plug it to charge. This help maximizing your battery charge.
2. Stop searching for a signal. When you are in an area with poor or no signal, your phone will constantly look for a better connection, and will use up all your power doing so.
3. Switch off the vibrate function on your phone, and use just the ring tone instead.
4. Turn off your phone's back light.
5. Avoid using unnecessary features. If you know it will be a while before your phone’s next charge, don’t use the camera or connect to the Internet. Flash photography can drain your battery especially quickly.
6. Keep calls short. This is obvious, but how many times have you heard someone on their mobile phone say, "I think my battery’s dying," and then continue their conversation for several minutes? Sometimes, the dying battery is just an excuse to get off the phone (and a good one, at that), but if you really need to conserve the battery, limit your talk time.
7. Turn off Bluetooth. It will drain your battery very quickly.
8. Same goes for WIFI, GPS, and infrared capabilities, if your phone has these features built in. Keep them off; save more power.
9. Use GSM - Using your phone in 3G / Dual Mode will drain the battery quicker than if you just use GSM mode - have a look at your phones spec and you'll see it will quote two different battery life times - normally 50% more for pure GSM use.
Very Important:
Anyone purchase a new phone. Its best DO NOT USE the phone with the little remaining power the battery has. It is best that you put the battery in the phone and turn off the phone and change for minimum of 5-6 hours.
The 1st charge for the battery is very important for lithium ion battery. Leaving the phone off will give the full maximize charge the battery can take. Normal when phone shows charge complete by integrator light or on the screen means its 95% complete. To complete the 100% charge you need additional 1-2 hours after the full charge integrator show. Having the phone off also help keep the charge. A phone that is on and charging will never get that 100% charge because there is alway a little battery being drained just because the phone is one even if its plugged in to a charger.
If you see your battery is not giving the same performance what it use to. You can try this method at least 3-4 times for 1 week and follow up every other month. Meaning turn the phone off and charge it every night. It is best if you can drain the battery to 15% or less before charging the phone.

10. Keep the phone off, it'll not drain the battery at all!
So one person says don't let it drop down low very often, the next person says let it drop to 15% all the time...
Personally I've heard not to let it drop low more often these days. The old 'let it decharge regularly' was talked about a lot 4 or 5 years ago... no?

I think you didn't understand a LI-ION battery!!!
1. completely false
2. I've a mobilephone also I wan't to use it!!!
3. Maybe... Have you tested it with a ampere meter?
4. A black display is always a good idea!
5. Why not buying a Nokia 3210 ?
6. Better: Don't use it for call.
7. Correct! (If you don't use a headset)
8. See Pt. 5
9. See Pt. 5
A few facts:
- a new lithium-ion pack does not need cycling through charging and discharging
- Limit the time at which the battery stays at 4.20/cell. Prolonged high voltage promotes corrosion, especially at elevated temperatures.
- 3.92V/cell is the best upper voltage threshold for cobalt-based lithium-ion
- The 1st charge is no different to the 5th or the 50th charge. Stickers instructing to charge the battery for 8 hours or more for the first time may be a leftover from the nickel battery days.

I second this as well. The tips given by nuc70st is only applicable in the old days with nickel based batteries (Ni-cd and Ni-MH), which for the past 5 years mobile phones have in general stopped using and have shifted to lithium varieties. Nickel Cadium and a smaller extent Nickel Metal Hydride suffer from "memory effect" so it was important to deep cycle the batteries to maintain its capacity.
Lithium batteries in contrast should be treated in the opposite. You should keep it charged up whenever possible, and fast discharging (draining its charge as fast as possible) actually does more harm than good. Most mobile phones don't discharge it fast enough for it to be problem, but plugging a lithium battery in a purpose made discharger is still a no-no.
I dont know if anybody else can try this with their N1 but I have recently noticed that when my battery does its initial.. drop to 95% before you can wonder what happened, I can charge it with the phone on and the green light stays on, implying that the phone is fully charged.
Then I turn the phone off and charge it, and the red light quickly comes on and allows another hour? of charging before the green light will re-appear.
I think i'll be trying leaving my phone on and on charge overnight and then turning it off while I get ready in the morning and don't necessarily need it.
The green light comes on before the battery is fully charged

I'm right and the other guy is dead wrong. Deep cycling was better for nickel metal hydride batteries, because it helped delay the memory effect.
No such issue for Li-ion batteries, plus charging makes Li-ion batteries HOT, which isn't particularly good for the battery. So numerous charges leads to less exposure to prolonged heating.

I noticed that just last night! Are you supposed to keep charging it until its 100% or stop it from charging when the green light turns on?
Cheers,

Okie dokie, ive had a wee look about and whilst there are several posts on battery issues i dont see much on this one ive come across.
Ok, first things first, battery usage seemed a bit high but nothing too major, still got me through a day, then it got worse, bit by bit it was lasting less and less time. so ive done a few wee tests with flashing other WM roms and WP7 and i think i have a good explination.
It seems if you leave it on charge all night it may not quite fill up, if you unplug it when the green light comes on then plug it back in it fills up propperly, if however you unplug it when the green light is on and isnt full, plug it back in again and then unplug it again before its full it reports on wp7 as being full, which it isnt, then it looks like your battery is draining like a comet falling out of the sky which of course it isnt, just just your battery isnt full to start with.
anyhow, it seems to get worse if you dont notice it not filling up, so if i fill it up to say 80%, then use it, and at some point during the day plug it in briefly but not enough to fill it up fully it then takes that level as the battery max, the next recharge doesnt fill it up until a restart.
So yes, thats all rather complicated and probably makes little sence to anyone but me but the point is this, for one reason or another WP will think the battery is full when it isnt, which makes it look like the battery usage is massive, which it isnt, it just appears that way because as far as WP is concerned, under the right circumstances your battery is perhaps half the size it really is
I'd support dazza9075 in his articulation of this undocumented 'feature'. Without having given it the same levels of consideration, I've had similar experiences where I have had a phone on the green light - I unplug it, take a short call, plug it back in and it stays on amber for another hour or more.
Elsewhere in similar threads there was a suggestion to soft reset at bedtime. I haven't done so rigorously, but the once or twice I have done, it does seem that there is more battery left in the morning.
Of course, in the absence of hard data from a battery percentage meter - assuming it is accurate - this is all subjective speculation anyway. But it is reasonably safe to say that WP7's battery reporting is immature at best.
Aye, not having propper access to battery stats is a bit of an oversight. Just to add to my ramblings just charged the phone, green light, unplug, icon suggests 100%, plug in an amber light pops on, unplug an Icon dropped to around 80%, plug in again and leave phone on standby it will charge, but as I type on here battery icon gone straight to full an green light on.
Lesson of the day, charge and don't use phone, keep repeating unplug an charge to get full charge back
Good stuff guys! Indeed; i noticed the same thing! Although when it says Low Battery i can assure you that the phone will still work for a day like mine.. i charged it yesterday morning; at night it said battery low and still now i am using it! Weird stuff but as we know WP7 is not meant to be on HD2! Someone here (member or dev) will fix the problem some day like Android OS... This is just the Beginning!
I can completely agree with the observations written above regarding the battery charging in our HD2s.
Just install the Battery Tool from the HTC test package found here:
http://forum.xda-developers.com/showthread.php?t=896104&highlight=test
Then when you open the program, for fully (I mean really full battery) there must be the following lines there:
Code:
Weight: 1000
RARC: 1000
Voltage: 4196 (+/-, different, this is mine battery)
Current: 0
Full: 1230
ACR: 1230
Last one (ACR) and Weight (1000) are the most important, so that ACR == FULL. After that I can use the phone for 2 and half days with moderate usage.
When the usually charging appear, after the green light, when I open the application it says:
Code:
Weight: 686
RARC: 686
Voltage: 4196 (???)
Current: 30 (it appears still charging with small amount of amperage)
Full: 1230
ACR: 840
For me here the battery is 2/3 full, but is strange that it reports full voltage, although ACR << FULL. If I unplug the charger, then just right after some minutes I'm starting to see how the battery indicator decreases fast.
EDIT: It seems that after green light, If I unplug the charger and plug it again, the above settings change dramatically, as well as indicator, showing 2/3 full battery:
Code:
MS_Percent: 69
PA_Percent: 69
Weight: 686
RARC: 686
Voltage: 4196
Current: 75
Full: 1230
ACR: 845
Then after 2-3 minutes it's becoming green again and MS and PA pointing to 100, BUT Weight and RARC = 686.
The question is, is really battery 2/3 full or is just wrong determination of charging percents (battery indicator levels) as noted above?
ah, very good tool
I think that just proves what i suspected, the phone dosnt have a clue what its doing, to get a full charge, simply unplug when green light comes on, keep screen off on standby and replug-in,red light appears until it thinks its "full" repeat process until ACR is full. A reboot will have the same effect it seems
Failer to do so makes phone results in incorrect battery stats and can result in the phone appearing to have a much hight battery usage then it really does

I struggled a lot initially then I did the following changes which made my battery last for 3 days, yes you heard it right.
1. Remove all live & Facebook (active) tiles from the home screen
2. Turn data/WiFi off when not in use.
yes, use the battery tool from htc to read and charge your battery to 100%...though it says 100%...charge until ACR reading and FULL reading are same or the battery current says zero....similar to current widget in android where the phone can be charged till the current is 0ma..meaning no current is passing between the phone and charger
Where do we get the battery tool from htc?
Edit: Foud the link in the above posts .... Thanx
Not exactly related but I have the same problem with charging, if I plug into my laptop it starts orange and turns green when its 100% but what it looks like to me is that when it thinks its charged it turns off the charger and the light still stays green.
So my battery starts draining but still showing green, if I unplug and plug back it will go to 100% but the same happens again.
Getting annoyed with this I got one of these...

My personal habits call for a soft-reset at bedtime (while it's plugged in) and a little video camera shoot when I wake. This yields about 18 hours of battery life for me with constant 3G and/or WiFi usage. I average ~12,000 texts per month.

which version of WP7 and radio rom are u using ? Presume its a EU HD2
Hy all,
Since some time I have big problems with my nexus 4 battery...
This problem is on all Roms and all Kernels for me, so I think this is directly a dead battery problem
WHen I use my phone, sometimes the phone shootdown randomly between 10% and 40% battery, and when I reboot it, the battery indicates 0% and shoot down immediatly after....
I tryed to calibrate, to put in the fridge (lol), charge via LG usb charger, via computer, via wireless pad, but the problem remains ...
Is it time to change the battery ? (PS my battery come from china)
Somebody can indicate me a GOOD battery reseller on ebay, or somewhere on the net, and who have express delivery in europe (not worry about price)
thanks a lot all
your real concern should be the random reboot...such battery drain is normal because the battery percent is only accurate right after a reboot. the battery drains extensively while on boot animation as well because all your cores and screen brightness is at its highest...so your battery is perfectly fine...for the random reboot im guessing its an app thats causing reboots..finding app = no reboots = better battery
Hello guys
I have my galaxy s4 i9505 android 4.4.2 . Is that normal, that my phones battery discharges in 2 h 30 min average (from 100%), when i play heavy games like asphalt 8 from fully charged battery till its discharge with wifi on and on 50 % brightness? Also when im surf the net, stay on fb and do stuff like that, my phones battery discharges in 4 hours. I say thats not normal. And by the now my phones battery discharges 1% in 2-1min
So its that a foulty battery problem, charging port problem or else? Dont tell me reset my phone cus, i done that 10 times already and it didint help
Im pretty sure its not Running apps problem either, cus my phone dont heat.

Let's be organized:
1. Faulty charging port: can be, if you phone charges too long. nothing related with discharge speed
2. Faulty battery: check battery SN, if it starts with BD letters, can be. In this case, the battery would be visually swollen, and your phone shall randomly reset with charge from 80 to 30%, and shall not be able to start without the charger connected.
3. Discharge of 60% per hour is possible, depends from the apps running in background. Install Battery Monitor Widget or something similar to investigate closer.

Thanks for reply I forgot to mention that my charging port is weird, sometimes charges phone, sometimes not. Recently my phone charges only when its turned of completely, when phone is on with charger connected its discharges. Also i can say that thats not a charger problem, because my brothers S3 charges very well with it. I'm i have ordered the new charging cable/part for my phone, and hopping to fix charging issues.
Another problem is that my phone in powering On process goes to Download mode without key combination and dont boot up (sometimes), also in the same way rondomly when i press power on button it goes to recovery mode (without key combination). Is that problem may be realated to this one i stated before (about charging).
It's perfectly normal. There is nothing wrong with your phone.

Really? 2.5h is good on gaiming and wi-fi with 50% brightness? When browsing the net, my phone discharges in rate like 1%/3mins... (average)
it depends entirely on usage. 2.5 hours screen time while gaming is pretty good I think. on stock rom i can manage anything between 1.5 and 4 hours screen time, but it also depends on usage during screen time. if you're running something that's quite hard work on the cpu/gpu and with the srceen constantly on....like gaming.....then obviously that will drain your battery faster than just browsing the web or texting etc.
generally speaking s4 will last through a days normal use quite easily.....but then it depends on how you define normal days use.

Thanks for reply So its nothing to worry about? I had S3 and it lasted much longer than my current S4. Of course i need to look at its 5'' display and 1080p resolution If you guys getting same battery life while heavily using your phones, it means it's ok and i don't have consider of changing battery ?
yeah i think from the sounds of your usage, that's about right for a stock rom.
if you are still only getting about 2-4 hours total use (i.e. battery dead from 100% down to 0%) from your normal daily use while you're at work/school or whatever (i.e. where it's sat idle for most of the day), then you've probably got something wrong. but given that you said you were playing games etc contantly and still got 2.5 hours screen time, that's ok i think.
you can always try and squeeze some more out using custom kernels etc, but if you are not certain it's some other fault i#d try and see what battery life you get on idle first so that you don't lose warranty by flashing a custom system. so yeah try for a day or two leaving it with just normal usage or idle whenever possible to compare

THAT is NOT normal... and yes, it may be somehow related... if your phone shows that often, and if it is under warranty, I'd consider going to service center
ooops, yeah i totally missed the post about your download mode issue and faulty charging port. if you're in warranty, take it back.
Hello!
Some time ago I found inside Advanced Charging Controller this feature called battery idle mode. When the ASUS ROG phone 3 was launched I immediately noticed the pass through charging.
Basically it is the ability to run the phone directly from the charger and stop charging the battery in certain conditions (like when the battery is hot, or it reaches 80 %). On the long run this could mean a big improvement in battery longevity, especially for people that use their phones while charging (overnight charging, in-car navi, gaming, etc.)
Sadly, this feature is kernel dependent. So I am trying to figure out if there is a kernel that supports this feature. I've tried searching around the development area, but there was nothing obvious and I didn't dig through the discussions.
Thanks!
Did you happen to find a kernel with support?
Sadly I haven't.
But I did find a different trick: set ACC to charge with 0 A (or any other very low value) and you'd basically get the same outcome (the battery will stay at the same value). Now I am not sure if this is in fact activating some trickle charging mode (and wearing the battery in the process)...
