So I have the neon400 from bell, have gotten a battery exchange once now because I figured I had a bad battery,
Battery life is roughly 4-6 hrs with minimal usage. which is terrible, With normal usage (about an hour of talk time), my battery is dead within 3 hrs.
I turn off bluetooth, as i heard it was a battery drain, unfortunatly push mail is on, and activesync for ms exchange.
Should also note that I have msn running pretty much all the time, but even with the above, i should still have a longer battery life....
Anyone can make any suggestions to improving battery life on my phone?
low life
I have a rechargable drill and flashlight set and on the instructions it states NEVER CHARGE A HOT BATTERY so I took it one step further and put the battery for my cell phone in the freezer for 10 to 15 mins before charging the only problem with that is. The battery sweats water when it comes out and you can cause water dammage to the phone and battery. I put tape on the battery to protect the contacts and wait untill it stops sweating before puting it in the phone to charge. Also, I cant say for sure with your phone but with my nokia 6275I phone it was using the battery during the night probably sending usage information to the service provider so I removed the batttery each night. After breaking in the new battery by giving it a full charge and waiting for it to be totally dead before charging (you must always do this). And cooling before charging and removal each night my battery was lasting for seven days yes SEVEN days. Mostly because no one was calling me and I was not making any other calls or using the phone in any way. Yes the phone was turned on and all other settings were off like infared and btooth. Also the phone was entering into low power mode at the end of battery life
soo good luck

I've noticed the same thing. I don't use my phone a ton, and usually every day it's charged into the computer.
However when I unplug it after work on Fridays, by Sunday night, the battery is dead....this after being in low power mode, and not being used much.
It would be so nice if there was a replacement battery you could buy that was better...
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.

all very good tips, but its just funny that to save battery life we cant use ours phones as they where intended for us to use them. I need dilithium crystals.

Ye, my battery just went from 48% to 3% in about 3 minutes. Does anyone have any idea why this is?
Same problem here. From about 43 % down to 7 % while it started to charge the battery with the original charger. Afterwards the Tab didn´t charge at all. Battery drained and got very warm.
I Called Vodafone and was told i have to send the Tab in for fixing. I hate waiting for the tablet 3 weeks.
Update: After 2 hrs. of waiting the Tab cooled down and i was able to start it again. Did a factory reset and was able to charge again with the wall mount charger.
Just wanted to bump this as my battery life is miserable and it discharges really fast in standby...
My HTC desire has been on for 52 hours, used for a lot of stuff and is at 20% battery.
The Tab charges to 100%, I unplug it at night and in the morning it has lost approx 10%, I leave it a few more hours and it't down to around 60%. This is with no use and no apps running!
I've tried killing apps or leaving them in memory and it doesn't seem to make much difference. I also use setcpu and have a profile where the CPU speed decreases when in standby to conserve battery?!
If I charge to 100% and use it constantly, I get fair life out of it maybe 4-6 hours of light use - some streaming over wifi, web surfing, kindle, sudoku etc. If I use it occasionally or heavily though, it dies very quick and if I leave it at about 40% on the evening, it's generally dead in the morning.
Why does it discharge so fast in standby??
Check to see if it continually searching for a signal. I've noticed that mine loses a lot of power constantly searching for a signal, cellular and wifi. So, I used airplane mode to conserve power. Remember that it syncs to different services that require it to periodically download data. That may be your issue.

Thanks Chuck, I use it in airplane mode all the time and only use web over wifi (bought unconnected in the UK). Would it still be syncing for email etc? I didn't think it could turn on wifi and sync itself but only when I turn wifi on. I always turn wifi off when not in use. I had problems with widgetlocker asking for superuser permission quite often and that killed the battery quicker so I removed that until it's fixed and saw an improvement.
I'm not seeing the times that other people are though, losing at least 10% overnight and there's nothing really running.
I installed battery doctor and the times it quotes are high for different types of usage and nowhere near what I'm getting.
I'll make sure email and calendar are set to manual update, adjust brightness etc and see what happens. It seemed better when I first got it so perhaps an app is draining it? I installed system panel to monitor this but it's hard to see what is actually draining it, any recommendations anyone???
Quite disappointed at the moment, ipads barely drop 1% overnight and I'd rather not have to turn it off to conserve battery when it should maintain it in standby...
Check the task manager and see what application are running. Also you can go in settings- about device - battery use to see if a specific application is using your battery out of normal. Also , the display is generally the battery hog, you may have set it to a super high level. One last thing you may have the buggy 3d gallery app, and it will show in the battery usage.
P_
this is an interesting problem. its very similar to the Apple Macbook Air.
The Macbook Air was very thin - very nice looking - however it needed to depend on wifi to do most things.
the association i am trying to build here is this: the Tab needs a bluethooth headset so you dont get all your calls broad-casted over speakers and that could drain the battery a lot.
for me the battery drainage didnt seem so bad and its been on for the last 36 or so hours. the battery icon didnt look like it moved so much and i was impressed considering this thing had a gigantic battery. then i loaded up a utility that read the battery and said i had 59% so my jaw dropped. not only is the battery indicator wrong there maybe rogue processes casuing the battery drainage. and this is on 2.2 which is supposed to be somewhat battery efficient.
i dont know - frustration is what i am all about here with this thing. it seems that every time i buy a new android device i want to move to another android device. no one is getting the damn thing correctly setup.
Am at work right Now, Charged the tab overnight, just few minutes ago my battery said 60% left and now the tab is completely dead, wont turn on, I ll wait until i get home to charge, fingers crossed.

I am experiencing the same thing. Tab on flight mode and charged to 100% overnight. Unplugged at 9am, still on flight mode with no apps running, and it is 88% at 2pm.
12% drop in 5 hours with no usage whatsoever is way too much imo, comparing let say to my HD2, even not in flight mode. Wonder if they have a bad batch of battery for certain tabs........
Just wanna report back after my last post. When the percentage was dropped to 85%, I did a reboot. And guess what, now it displays 95% !!!!!!
5% drop from the morning til now in flight mode seems right and okay. Does it mean the tab is miscalculating the percent left?
PS.
I have been following the voltage in Spare parts this morning. All settings are the same (no apps opened, same screen brightness and in flight mode. Only turn on to record voltage)
94% - 4087mV
91% - 4081mV
88% - 4075mV
85% - 4067mV
But then after the reboot
95% - 4040mV
Man, I am not sure whats going on here........

let me jump in here again and share a similar deli-ma i had with my X10i.
while i was messing around with some custom roms i decided to stick to one that looked somewhat nice. well the funny thing is the battery indicator would always display 100% and for about 4 hours it would drop ever so slightly. then i removed the battery and put it back in -- the battery indicator showed 0% and i got a red light flashing ....
after screwing around with it for a bit i re-flashed the stock firmware from Sony-Ericsson and magically my battery meter and my battery worked fine.
so to sum up -- it maybe a software issue like the one i had on my SE X10i above?
Hello,
So I've had the V20 since it first came out and I'm loving it. With the stock battery, I'd charge it every night and not notice many issues. Noticed a respectable 3-4 hours of SOT, which is decent but not spectacular. Then i got the Zerolemon 10,000mAh extended battery for it and I still feel like the phone doesn't have the battery life it should. With the extended battery in, I would sometimes leave it unplugged overnight and lose 15-18% (which, in a 3x battery, correlates to almost 50% of a stock battery) in just one night. So i'm wondering, any apps/servies that just guzzle battery overnight? Any info is a help, thanks!
Good possibility that the new battery you have may be junk.
But you'll have to pop the stock battery in and do battery usage comparisons between the two.
Have you calibrated the Zero Lemon battery? Run it all the way down until it turns off the phone. Pull the battery and then put it back in turn the phone back on to make sure the battery is drained all the way.
Then recharge it without disturbing it. Recommend doing this overnight.
Also make sure you aren't switching batteries once you've got the lemon calibrated otherwise your battery gauge won't read accurately.

Have you calibrated the Zero Lemon battery? Run it all the way down until it turns off the phone. Pull the battery and then put it back in turn the phone back on to make sure the battery is drained all the way.
Then recharge it without disturbing it. Recommend doing this overnight.
Also make sure you aren't switching batteries once you've got the lemon calibrated otherwise your battery gauge won't read accurately.

Yeah i might have to, i've been trying to avoid that. I honestly think that it's the phone not the battery, because when i leave it alone overnight it loses like 12-16%. Losing that even off a stock battery is ridiculous so i figured it was something with the phone that caused it to run all night without dozing. i read up on some threads about wakelocks after installing GSam and seeing that the phone is held awake quite a lot (as i type this, i'm sitting on 72%, 13h16m of usage, 3h5m SOT, and 4h28m held awake. So i honestly think it's the phone, but then again if i do drain it down then do a battery pull and it jumps up to 30-40%, then i'll know it was the battery
Also, would you recommend once the phone shuts off plugging it in and leaving it off, or turning it back on once i plug it in?

Don't think its the battery, it's highly likely the ROM you're using. I had terrible life after the last update.

I'm running bone stock on everything, no root
Update: been getting significantly better battery life after doing two things:
1. Turned off Bluetooth location scanning (I already had WiFi scanning turned off).
2. Using my phone without WiFi on (on the chance that it might be the WiFi causing wakelocks, which is something I researched a bit with the help of GSam. Wifioffdelayifnotused was the suspected culprit).
I'm not sure which one could be the bigger factor, but I'm going to leave my phone unplugged overnight with WiFi off, then after tomorrow night when i charge it fully again I'm going to see how much battery life I get with WiFi on (this way I should be able to determine if it was the Bluetooth scanning, or the WiFi.)
Any input would be appreciated. Thanks!
Had a zerolemon on my Galaxy S4 and while it was a great battery that added a lot of additional life, I never felt I got enough extra life that corresponded to the amount of mAh that the zerolemon brought. Though it wasn't anything like what you are describing. Just never felt like I got 3x the battery life even though it was like 3x the mAh amount but maybe that's just because I don't understand the whole science behind the mAh ratings on batteries.
Update part 2: turning off the Bluetooth scanning and Wifi (only yesterday, had wifi on today) has resulted in much better battery life so far. Oddly enough, early on it seemed a lot better, on pace for almost 15 hours SOT. I'm at 18% now and almost at 10, but still pretty good and better than what I was getting. I'm chalking it up to the Bluetooth scanning since I use an Android wear watch that I leave always connected. I'll do another full drain tomorrow after charging it tonight, this time leaving wifi on to see how much of a difference the Bluetooth scanning makes (3rd pic is early on when I was on pace for 15h SOT; left phone unplugged last night and stayed at 64% all night. So my 12-18% overnight drain (40-ish% on stock battery) problem is cured )
hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state) .this situation's screenshot is attached and named : Screenshot_2018_01_21_07_05_15.
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test [this situation's screenshot is attached and named : Screenshot_2018_01_21_07_49_27] )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.
Hi all,
Since a few days I have a huge battery drain om my Fossil gen5. It never was the best battery, but it lasted from 6am till 9-10pm before it went in battery saving mode (without sport exercise)
Now it's already in batt saving mode after 10 hours .
Everything is "on" except WiFi, nfc and OK google detection. The same settings and apps as a month ago.
Are there any tricks/mods/custom roms to extend battery life without compromises in functionality?
I already did a reinstall, but unfortunately it didn't affect the battery life.
Hope someone can help me

Other than turning off things like Location (as you already have Wifi and NFC off), not too much else than uninstalling apps you don't need, and turning off Notifications on most of your apps except the main essentials you want.
Turn off Always On displays, or the Tilt/Tap to Wake (they do consume more battery and it's just as easy to hit the main crown).
Only turn on Location/etc when you need them rather than on all the time.
Also the little battery inside, if you've been using it from 0% charged to 100% the whole time, instead of keeping in in 20% ~ 80% (ie: not charging more than 80% or so), the battery itself will deteriorate after a while. Keeping it between 20% and 80% typically keeps most Li-Ion/Po batteries healthy longer. (kind of why wireless ear buds can't hold a charge anymore after 2 or 3 years).
