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.

I had this with even 30%. the battery was old and defect.
Buy a new battery.

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.

Dead battery/Won't charge fix

Ok, so last night after work, I realized my phone was dead. So after getting in the car I connected the charger only to get a blinking amber light. It wasn't the regular slow/rapid blinking I usually get from a dead battery. It was very quick and intermediate, and wouldn't charge at all. Well leaving it on the charge overnight didn't help so I ordered a new battery. And since I'm so impatient I came up with something so I wanted to share
I looked at the battery and found a negative and positive symbol. From there I got to thinking. "Can I use a battery to charge the battery?" So I grabbed a AA out of the remote and some wire and connected the terminals. low and behold nothing happened.
A AA battery only has 1.5v and on my charger it puts out 5v. So I grabbed some other batteries and put them together (3 total for 4.5v). I don't want to go over 5v into the battery. After a while I put the battery in my phone. Again, nothing.
So I thought. "What if I connected the battery to the battery to the phone" Kind of like a jumpstart. (See picture)
BINGO!
I now have a solid amber light. And right now as I write this I am letting it sit. I don't wanna screw it up lol. So I will provide updates as it continues.

that's more battery effort then i think most people would put into.
as was said in the samurai showdown games... VICTOLY!!

Well, going back to a blackberry gives all the motivation in the world

Sounds like a kernel issue I had a few bad kernels in the past that didn't allow me to charge if it was a bad flash. I would invest in a wall charger and maybe 2 extra batteries on ebay easy way to charge your batteries outside your phone.

Well the battery will drain itself in a few hours. I have tried other kernels and roms. The new battery will help.
But as for now. I have to go back to stock because I need to get it reactivated. I hate verizon.

it's funny because if you walk in to a Verizon store with a rooted phone and show it to them they get all excited and ask about the rom, etc & may even show you their rooted phone. had that happen with a manager who was intrigued by the das bamf rom i had on my thunderbolt awhile back.

Haha I'd be too scared. The guy I saw today was cool though and they usually aren't.
I have boot manager so my rom is still on my sd so it's not like I lost anything.

That's gorgeous... hahaha.

This is the understated truth of the year. I just inherited my mom's thunderbolt and I was previously using my BlackBerry 8530.
Never going back

oh hey, wanted to also mention that sometimes those pins that make contact with the battery can bend slightly and cause the battery to not charge/phone not turn on... i've had to take needle nose pliers once and "fix" one of the pins.
also, if you take a very small amount of automotive 'spark plug grease', and apply it to the connectors, it ensures a good solid contact. (it also works putting it on the antenna pins on the back cover).
just don't use electrical spray otherwise you'll have weird grease stuck behind your screen like on mine. ^_^

i know this is old but dude u just saved my phone

And mine too. The minute I get back home to try it. My girls phone died after a quadruple restore,bootloop,battery pull debacle. On the 3rd battery pull couldn't power up, get in recovery or even use adb. Had to put her back on her old Droid charge amd man she missing that tbolt.

[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?

Do I have a bad battery?

So... Starting yesterday, about 5:00pm, my battery started charging extremely slow. I plugged my phone back up since the battery went down pretty quick at about 9:30am in the morning. It went to 30% battery and from there, I don't view if it's going up anymore. I took a screenshot at 9:42am and once closer to 10am, also taking another as I typed this. I've also tried 2 different chargers, and multiple outlets.

@rootSU, sorry for tagging you. You just seem to be extremely helpful, and reliable. ?

The last screenshot, I just hit 31%... Literally changed when I clicked the battery tile.

When you tried multiple chargers, did you also try different USB cables?
You need to rule out if it is slowly charging or if it is draining quickly whilst charging. Try turning it off and charging.

I attempted that yesterday when I first noticed it yesterday. I plugged it up, and left it off while I went to the market.
I left it plugged up, and I'm now at this from earlier.
I'll attempt that now with another cable.

I'm now at 100% after letting it charge while off.

The device is still doing doing it. Seemed to charge faster from USB earlier, but now it seems to be back where I was earlier. I'm starting to think that maybe the charging port is the messed up part of the phone.

This is why I asked you to charge whilst off. It rules out software as an issue if the same result is seen. If you've changed the cable AND power source, it can only really be the port.
Is it stock unrooted?? Does seem like the kernel gets involved in charging whilst off too , so if you're not stock, I would consider reverting to stock.

I swapped back and fourth between cables and reboots after returning to stock. I went to stock 4.4 and upgraded all the way through. I then noticed it started to charge faster, or the battery actually read that it was going up. I had Current Widget on my home screen which seemed to be pushing around 900MaH the whole time.
For now, it's back to normal, I believe. Thanks RootSU ~:good:

is it back to normal?
my phone is doing the same take forever to fully charge but i dont know if its the battery or the port

Sorry for the late reply, it I've downloaded CurrentWidget where I can see the mA output. The OEM charger seems to be pushing out at 20-300mA. I've plugged up yesterday to an old HTC cable that I have, and although it's all beat up and near its end, it's pushing out 300-600mA.
I believe the original OEM output is near 1000mA. Possible that it was my charger that was faulty. I've been using a lot of different chargers in the past week testing with the mA's.

[Q] phone shuts off before 0%

Hi, Is there any full proof method of fixing my phone battery so it shuts off at 0%?
My bacon shuts down at 8% - 4% usually.
and when it does shut down it blacks out. I don't get that pop up with a spinning circle saying you're phone is not shutting off.
Well, unless thats how the OPO shuts off by just immediately blacking out?
I checked to see if it was because my undervolt, so i brought back the voltages to stock, and unfortunately, the problem still remained.
I know you arent suppose to run these batteries dry, but it just irritates me that it would shut down at the 8% mark.
So any suggestions and fixes would be greatly appreciated!
Thanks

If you know that, then why the hell would you want to do it just so that you damage the non-replacable battery and potentially leave yourself with a brick?

The battery percentage displayed on your phone isn't exact, not at all, it's only an estimate based on the voltage level it's detecting at the battery. So if your phone shuts down at 4% it really isn't a big deal. If it's bugging you so much you can use a battery calibration app from the Play Store to try to re-calibrate the battery.
But, if you're letting the device get that low regularly, which it seems like you are, you're damaging the battery. You even admit that you're aware of this. So why do it? Running a lithium battery down regularly decreases its capacity, just like keeping it at peak voltage too much does too. So it's entirely possible that what you're experiencing is a symptom of your own bad battery usage behavior.

Gee, I don't know
Maybe I like to see a full screen on time, testing kernels and roms?
or maybe, I didn't expect my phone to shut down at 8%, so I wanted to see if it wasn't just a one time thing because the unknown piques human curiosity
Maybe as a newer model phone, I'm putting some faith into solid build materials from the phone?
My nexus 4 has been run down many times naturally being at school or work and what not, and the battery still runs like a champ.
