my magician switches off while battery is over 10%

hi somebody, i am having a problem with my O2 xda2 mini, i've been using it for over an year, what happens is it switches off automatically, while battery is still over 10%, and i cannot switch on it, it justs fades and fades to darkness, when i only connect to external power it come, help me let me know what i should do. pls

how abt charging the battery when it reaches at 20%!! why u letting ur battery reach 10%? u can charge it whenevr u want. the Li ion battery does not have a memory effect. u can top it whenevr u want..

Magician is not supposed to run dry. Also, AFAIK, I think Li ions aren't supposed to be run dry, damaging I think.
Magician will automatically shut down extraneous functions to save battery and preserve sufficient juice to maintain memory for a few hours despite your efforts.

i know, but there might be instances that i might not be able to charge but i think 10% is more than enough if i am not making any calls or not doing anything with my magician. anyway i'll recheck my battery if i need to change i'll do so.

asinan: you might think 10% is enough, but Microsoft don't. And for good reason.

So buy a new battery has solved ur problem?

I had this on my Magician too. At about 30% or so... I bought a new battery and sold the device right away, so I never found out if that solved the problem. But...
I have switched to a Mio device, and on their site under Support, I found some interesting info. If you fully discharge before recharging, the battery will live for 300 charges. If you recharge at 30%, it will live for 20.000+ recharges! It doesn't get any clearer than that!

May not be a battery problem
I'm having similar problems. Initially it goes off when the battery level drops below 50%. I bought a new battery and even at 99% the device goes off. Now I have to press and hold the 'ON' button for it to boot up. I am taking it for repairs since I am convinced it is not really a battery problem.

we have the same problem .. any help ?

I got the same problem, but I solve it myself, don know it work with your phone ornot
A day, I take off the back cover of battery when it is working, device off. Then it is on normal, but some time, it turn of automatically. I try to make the back cover and the back of device clean and take of the protect film of LCD, then now, it work OK. I am lucky

Please let us know the outcome of your repair. We have the same issue at 40% and I am not sure whether a new battery will solve the problem

Ive just changed to a new battery and found out that my old battery was swollen up a bit on the surface. Comparing to the new battery, the surface was flat. So if you have the same problem, maybe you should check your battery shape and condition first.
Good luck.

Your battery might be lying to you

Okay...?
The majority of the people here have rooted.

It won't help. I have deleted the batterystats on mine phone more than 20 times in the last 3 days and there is no change nor hope!

Let me rephrase by saying your ROOTED phones battery stats might be lying to you.
And for the guy who tried it three times and failed. I don't think you took the time for fully discharging the phone. That's right I'm calling BS.
Anyway got to go my battery just dropped 30%

Just wanted to let you guys know that this is completely true in my case. The other night around 2am I went to sleep with the battery around 68%. When I woke up 4hours later for work my phone was turned off. I then plugged it in and my battery was at 0%.
I was on the perfect storm Rom. I then switched to das bamf. Still happens. Tried bump charging and 0-100 charging and its helped but when I reboot the phone the battery shows about 7% less then where it was.

I think that is thy the stock battery icons don't show an exact %, b/c they haven't been able to make it work right. Don't worry though i believe that the devs will get it before HTC.

Ok my battery was just now at 50%. I restarted and now showing 41%. I don't know what's going on.

As I said, you can charge and discharge all day long, it won't help!

Thank you for reposting this. So sick and tired of people complaining about dropping 10% in a few minutes after a full charge.

I think this is a glitch. It drops like crazy after restart but then stays there until it "catches up" I guess.

So far,I have only rooted my phone, not a custom rom. I either have a crappy battery life, which seems better when I shut 4g down, or there is a glitch on the metering. My .02 worth.

Battery dies then back to normal

I have an issue with my battery. Sometimes it starts to drain the battery VERY fast, like 80% in 20 minutes, then the battery dies and the phone turns off. But if I turn it on it starts with the ammount of battery it was before the crazy descharging, and the phone works as usual.
It is a pain in the ass because every night it happens, so I cannot set an alarm. Sometimes it happens in the day too.
It is upgraded to Android 4.0.4.
I forgot to say. I bought the phone and tried to update it. Something went wrong and the battery was low. So I coudnt use RSD tools anymore. So I opened the phone and did that force recharge thing to charge the phone up until it had enough energy to use RSD Tools again.

Might just need to clear battery stats. I'm guessing you didn't do a factory data reset after you took the update?

Hi. Yes I did a factory data/cache reset...
I cant see the pic i posted, so I will put here the link of it in google docs:

Hmmm. If you've done a full reset then it looks like it's an issue caused by the update itself. I've never seen a battery graph that looks like that.

its better to use battery calibrator app from market and use and u can also make 3 complete charge and discharge cycles and see ......if it still doesn't work then it should be a bad battery ......replace it
CHEERS
HIT THANKS BUTTON IF I HAVE HELPED

you should replace your battery

It's been shown that all of that multiple calibration mess is bunk. Except in the case of errors battery stats are cleared on reboot anyway.

A new battery would be a better option, ok try one thing , take off the battery and keep it in the sun for 2 hours, then charge it full .. Use this.. N seee

I had a similar problem with my second thunderbolt. Finally I replaced the battery and problem was solved.

[Q]My DesireS charges extremely slow

Some day over a year ago, realized my new Desire S just charges extremely slow.
It usually takes a whole night(10+hours) to charge from 10% to 100%.
In the past year I tried replacing a new battery, different wall chargers, wires, roms, kernels, even HBOOTs, the problem stays the same.:crying:
Now I have to use an extra battery and a desktop charger to keep it alive.
Everything is running great except charging. Even battery duration is fine.
What should I do? I really want it repaired.
Or is there any rom or kernel that forces charging current?
The snapshot is my DesireS charging with my new 1200mA Nexus4 wall charger and wire, offscreen.
When screen is on, charging current is lower than 100mA.
Current:180mA, estimated 2h27m from 76% to full.:crying:

Hello!
I have the same problem with charging. Using special soft I mentioned that my Desire charges with max 130mA.
I've tried it with tree accumulators and a lot of charge-cables but no effect. Please help.
Thanks

i have some problems about battery too. what can i do?

I had that when I bought a second-hand desire S, i tried multiple ROMs/kernels but no avail, later on i found out it was the battery that's dead, slow to charge, fast to drain, if you can't get through 1 day at least with it, change the battery, it's cheap and it'll solve it, you could try another battery to verify that it's the battery and not the charging circuit, but from what I had to do, change the battery, and get the OEM one not a 3rd party battery, good luck!

Do you have any suggestions? Maybe somebody goes to service center?

You are using 1200mA? In snapshot titled 1600, which is it true?
In the middle of charging, hv you ever rebooted the phone?

[Q] Please Help!!! Battery shoots up automatically.

I usually flash custom roms on my device. But my device has one unusual behaviour. When I charge my device and suppose it is 70 percent charged and I reboot my device within 20-25 minutes, the battery level shows fully charged. (100 percent) After that the battery drains within 2-3 hours. Because of this I charge my device 3-4 times everyday. This happens on every custom rom I install on my device. Should I change my battery or is it the device's fault? Please help.

the percentage increase after reboot is a htc common issue while charging
about the fast drain maybe your battery is dying or doesn't makes contact properly
check it

Thanks for providing this useful information. Do you mean using paper or something that holds the battery tight or I misunderstood something.

exactly that
use something to hold the battery and see if you still have reboots

Actually I think the paper solution won't work. He's not having reboots, just the battery is draining fast. It looks like that your battery is almost died. I think you should buy a new one. And I highly recommend Anker's one.

Thanks once again. Will try.

I didnt want to make a new topic but I have similar problem:
i switched from standart ROM to Cyanogenmod 10 nightly builds for my Sensation Pyramid (original battery, about year old).
Everything worked fine, but there is one more than annoying problem:
I charge phone to 100%, i pull charger out. If i use standard things on phone (settings, gallery etc) everything seems to work fine. As soon as I enter any applications (Twitter, Facebook, default Web Browser) it just shuts down in 20seconds or in 2/3 minutes (always some random time, i can browse web 10 seconds, it shuts down, sometimes i can do the same for a minute and then it shuts down), it doesnt reboot just shuts down.
When I turn it back on, it shows battery level ~ 9-15%. It was 100% just 3minutes ago. I charged it for hours before, so that 100% should be real. I tested with battery drain monitoring app, when i use any apps, battery drops for like 1200% every minute. Its Ok on standby mode.
When i just reboot the phone, it comes up with some random battery percentage, f.e 47%. So it can go from 100% to 7% and after reboot it goes to 47%.
I thought it might be a ROM problem, so I installed this albinoman887 ROM http://forum.xda-developers.com/showthread.php?t=2115520
Did factory reset, cleared cache, phone was 100% charged. But the same problem.
I dont thin its battery problem, because it was OK with stock ROM. Is there anything i can try to fix this problem without going back to stock ROM (or other Sense based ROM)?
Here is a screenshot from my "About phone" section:

Really no advice on this?
Im not so good with Kernels etc., but my guess is- maybe this has something to do with CPU usage? I checked with CPU Spy app, it says Internet explorer, other apps use 1566MHz. Isn't that too much?
