battery emties very fast - 8125, K-JAM, P4300, MDA Vario General

hey everybody...
i never changed my battery in my wizard and i think it might lost his recharebilety
because when i turn on wifi the battery last only for about 50 minutes boefore it is empty.
is that normal? or do i need tio change my battery?
thanks

Well... the wificard drains your batt fast, but in 50min... that's pretty fast!
You could try to flash a carrier (original) rom, and then flash your favourite custom rom. But I personally think your battery has died a little bit, it's not new anymore (I guess).
Maybe a few full drains and recharges will revive your battery... But Li-ion and LiPo has, just like other batteries, it's limits and lifespan.
Goodluck.

Battery drains faster than it should

Hello there,
I would really like some advice - my battery is draining like water. I'm quite convinced it is the regulation of the unit; I bought a 2400mAh battery replacement and it lasted ages on first go, but then my G1 started draining stupidly fast after I'd recharged it. This also happens on the stock battery too (buy even quicker!). I'm convinced it is the regulation because a) I've never had battery problems previously and b) the battery meter starts at about 26% when I plug it it in (after the phone shuts off from it being dead and I then plug in the charger).
I actually have a bricked G1 that still charges batteries, so I thought I'd do an overnight charge on the battery that way, to 'remind' the other G1 what a 100% battery is like, but that didn't seem to work either.
Can someone help? Is this a known problem? I would really appreciate any advice.

Things that cause ridiculous battery drain;
Backlight, keep it at no more than 30%
Wifi - turn off search for open networks,
Gps - wow does this drain

GPS doesn't really drain battery unless it's actively being used...at least not on my phone.
You can also try disabling 3G if you're not in a 3G area. It will keep trying to find a 3G signal, which really drains battery.
For the record, I have a stock battery that I get ~13-16 hours on from a single charge... my backlight is at 40%, GPS is always on, and I use wifi whenever I want to surf the web and am near an open network.
OP...if your battery is lasting you only a couple of hours, then I'd try to reflash your ROM. Might help...
Wow 13 to 16, I am lucky if I get 6 with 30% backlight, and wi-fi and gps off, I have always gotten that on ever rom even stock with no widgets, you are one of the very few with good battery life cause I have seen many complaints about short battery ranges

Yeah, that's on a normal, moderate usage day. If I use it heavily, with a lot of wifi and web browsing, then I'll get around 10.
Maybe your battery needs to be replaced... could just be old and not holding a charge properly.
It's 2 months old, has done it from day one, I also have another battery that does it too that I kept from a previously brick g1, so one 3 phones, all the same battery life but then I use it quite heavily, always browsing on the web since my computer burned out

try that? 3rd gen battery could help..
Thanks for the suggestions, but it's not a wifi/3g/brightness etc problem - I've had a G1 for six months, I know exactly how much power should be consumed. It's also not the battery; I have two stock batteries and a brand new 2400mAh battery, which for the first few charges lasted about 2 - 2.5 days and was brilliant (as it should be), but now doesn't last all that long.
I may have made the situation slightly better however - I did a Nandroid backup, wiped to factory (well, Cyanogen 4.0.4 anyway) and booted into that. I then restored the backup and when I plugged back in to the charger, the meter was at 85%, and seemed to take a normal amount of time to charge (and not jump to 100%). It remains to be seen if the problem is solved, I've yet to have the battery drain (this is a good sign though) an plug in the charger to see if it will jump from 0 to 25 or not.
I'll re-post when I know.
run the battery down until the phone shuts off without plugging it in.
charge the battery while the phone is off over night
do this 3-5 times and see if you get any improvement.
also remember some of the cheap 2400 batts from ebay and such claim 2400 but that is from 3.5V to 3.0V. The G1 considers 3.2V to be dead so you only get from 3.5V to 3.2V which sucks.
I'm with gridlock on this one. My batteries suck. It always needs a mid day charge. And to the poster that said to reflash a rom, that is bad advice. There is known issues with getting poor performance out of these batteries. I have 2 and both do the same. Got the second one from complaining to t-mo about how bad it sucks.
Reflashing seems to have worked...the 2400mAh battery seems a lot better now, it lasted nearly two days (it runs at 3.7v, according to my battery diagnostic), I've only just recharged it last night. When I plug it in, it charges normally and linearly now, instead of jumping straight to 25%.
So my advice, if anyone is having similar problems to me, would be to try a reflash.
Thanks for your help everyone.

Battery draining fast and extremely slow charging since flashing.

Had my wildfire for a few months now, finally decided to root and flash a ROM after my service provider failed to roll out froyo. It's all been pretty simple and I've had no real difficulties, but my battery is now draining at a stupid rate.
I mean, with all the typical battery draining applications/services off it is still draining faster than pre-flash with all of them on. Literally like 1% a minute while hardly doing anything.
I've not bothered to overclock, even went so far as to underclock processor, still to no avail.
I've tried a few ROMs now and they're all the same, currently running 6.1.0 wildpuzzle. It doesn't help that I have a slow charger (original broke), this normally would do a full charge in around 10 hours so I'd leave it overnight. But now the battery drains nearly as quick as it can charge.... I've not even had it at 100% power since upgrading to Froyo.
Any ideas how to fix this? Obvious suggestions will be to try a fast charger (will do tomorrow round a friends) but I cant see this making a difference other than making it possible to fully charge and waste again in an hour after unplugging.
Battery life was typically 8-48 hours previously.
Ok, so I've finally got the battery to charger to full. However, the voltage reading is given as 4V, whereas is was previously around 4.2. Battery isn't fully charged. WAT DO? :\
Check my solution for stock 2.2

[Q] Battery Meter on Mango Inaccurate?

So i recently flashed CleanDFT ROM, first couple of days the meter read out 1 day and 18 hours which im very surprised then it went down to 1 day and 4 hours, now this morning i unplugged and it tells me i got 19 hours left from full charge, should i go by this? or is there something wrong?
hello can you help me wid flashing...i came from android...no idea of how to do it...

Redirecting you to the right place.
If you have just flashed a new rom, in general, you need to go through a couple of battery cycles before the battery read can be accurate. I remember when flashing my ATT FUze I had to wait 2-3 complete charging cycles ie. discharging battery to 10% and charging back to full before I could get accurate reading. If you are experiencing worse battery time than before flashing after 2-3 cycles you might need to reflash the rom; you should see better battery time with custom roms, so I have heard.
I also wouldn't go by the battery saver timing, I would go by wpbench or real time use to get an accurate reading on battery time. I have a 1800 mah battery in my focus and it reads 24 hours on battery life
As far as i know, doesnt all the ROMs have basically the same battery life?
Ill be going out of town sometime this week and ill be out most of the day, i need a rom thatll at least last a whole 12 to 14 hours at the most or whole day at best of just occasional twittering and occasional checks on facebook and probably capture some pictures and a video and maybe an hour at most on music? im sure this phone can handle it but idk what you guys suggest
I have the same issue with ATT samsung focus with Roger latest updates, the battery meter is just not accurate, sometimes full and just reboot upon eject from the micro usb. The battery was fine until recently. Found a few other with the same issue online, no solution available yet.
*pulling out battery doesn't work*
The solution is exactly the same as it is on a laptop.
Lithium ion batteries, and, actually, come to think of it, pretty all rechargeable batteries lose capacity over time. The phone, to begin with, doesn't have a good idea of how much capacity is left, and it has to estimate based on previous performance. This is partially a result of battery manufacturers going as cheap as possible with the circuitry in lithium ion batteries.
The phone needs to figure out how old your battery is. This data is definitely lost with a new rom. Leave it to charge overnight, then unplug it and let the battery run all the way to dead. Charge it again, and your battery percentages should be correct. It may take more than one cycle, but the meter should settle into a correct estimate eventually.
Incorrect battery stats are a possible reason for fluctuations in battery life and reseting them as described in the previous post can help.
Another thing which you can do is use an app like this http://forum.xda-developers.com/showthread.php?t=1328730 to check the reported mV rating of your battery at full charge. That can serve as an indicator of the battery life you can expect with your current battery stats.

[Q] Nexus 4: strange behaviour with new battery

Last week I got a new battery installed in my Nexus 4. I was using the original, around 2 year old battery, and I found it would drain very quickly below 50%. I had a shop install the new battery for me, I don't know if it was an official LG battery or not.
I ran the battery down to zero percent my first night with it, and have charged it at night ever since.
When I unplug the battery in the morning the battery percentage will suddenly drop down to 88-94% in about 1 minute. After this the battery drains normally and I get good battery life.
Today I tried charging it back up to 100% after it had dropped to 88 %. It charged to 100, and drained normally down to 95. Then, in a minute or two, it dropped down to 84, and has been draining normally.
Battery life is good, but the strange behaviour makes me think something is wrong with the battery. My question is: is something wrong with this battery, or is this normal behaviour? If it is, than I can ask them to give me a new battery. All this is with the stock ROM. I flashed 5.1 since getting the new battery.
Exactly the same here: Old battery made a worn-out impression, so bought a new one. Actually tried three different new ones from ebay now, all do the same: They charge up to 4.3V around, and when unplugged drain to 87% in a few minutes, i noticed the voltage going down to 4.0/.1V mostly, too.
The current battery seems ok from battery life, but i want an even distribution of the battery status, no matter the voltages - how can i achieve/fix this?
Same here.
Are there any solutions for this issue?

problems with battery measurer of s3 neo (i9301i)

Well.
My phone an i9301i (samsung s3 neo spain).
My battery anker 7200 mah.
My ROM now is cyano 4.4.4. Optimized with vulpix rc4.
My problem.
When i use muy phone.. The battery drains quickly. For example facebook in browser intermitently in 8 hours can drain an 50%. I know that battery can do 12-16 hours of screen up. I unplugged The battery from the phone and when the system is up. The measurer of the phone marks an 85-90 %. I'm crazy....
I calibrated the battery in every posible way view in internet and nothing works.
Any ideas.
Is an ROM bug?
Is the ROM only prepared for the stock battery of 2100mah?
Thanks and sorry for my english. Im spanish
Well there ware similar problems before dating to older unofficial CM days that battery doesn't change up to 100% properly. Regularly normal boot up uses 2~3% of normal battery. Chrome does eat battery abnormally much more than web view or Gecko based browsers. Think you're results are actually as they should be concerning SOT time wile browsing but I don't see a reason for complaining there. I use regular sized Anker 2200 mAh & on Official CM12.1 my SOT varies from 4+ h to 6+h depending what I am doing with it & where I am.
I don't know whats the problem. But android shows a battery drain abnormally faster. The battery charge is normal.
Why the difference is much bigger. When the battery arribes a 0 the phone is off...... But in the battery there is an 30-40-50 % energy ....
Im crazy...
Well it actually is regulated by the voltage level & not a capacity... Switch the ROM.
anker battery 7200mah i used too...
just with replace trick was used all capacity of battery
replace the battery and continue use of it... u have higher % after replace and reconnect
Zola. I"ve installed cyano 5.1.1 official. I will say if goles wrong por well.
Needforspiz..... Thats is what i do. But its not the best thing for use The phone. I wish the correct use of battery measurement.
Thanks for yours answers
Somehow android notify the battery is 7200 Mah??????.
i think that this is a value android not change.
The battery has 4 months. The phone has 1 year and half.
What's the problem. Phone or Android?????.................................
Thanks for answer me.
