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.

Your battery might be lying to you

it says if you're using custom rom...
i'm not ... nor do i have an ability to remove batterystats.bin from data/system either since i didn't root my device just yet...

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.

Phone overheating - very poor battery life

My N5, running XtraSmooth + stock Google kernel recently started heating up a lot. Now I know its summer time and naturally it would tend to get hot, but my father's N5 is always very cool to the touch. Even in an air conditioned house running a stability test brought my N5 to temps as high as 86°, whilst the other N5 was just about hitting 50°. My battery gets notably hot too, and of course that hinders my battery life too. Does anyone know what's going on?

My guess would be you have an app/process running full wack on your phone running up the CPU and draining battery. Look at battery stat screen maybe that will help. Try factory reset and run it empty for 30mins or so (no account no apps) then set up one account and app at a time.

Android malware/virii are on the rise, and I was hit with something that did this but did not show up on the battery monitor of any app.
I strongly suggest an immediate full wipe and clean flash, as well as changing your passwords if you truly want to be safe.

Hey, I tried that earlier today but to no avail, battery stats look normal, Facebook is the only third party app that uses battery, but only 2% at that too. It's only kept the phone awake for 50s, and CPU total is 2m so it doesn't look like its Facebook, but my battery still idles at 40-45°. I wiped and started again from scratch but first I let the phone set for 2 hours to let ART finish carrying out any optimisations so the phone could cool down and perform optimally. Antutus stress test still ramped my CPU all the way to 80° whilst the other N5 hit 71° this time around, it quickly went back down and cooled off quickly yet my Nexus took forever.

Mines stared to do it too I'm on stock and ElementalX. I've hit 85°C and as it's still rising turned it off. I've seen a few reports of this. I've no idea what it is but suspect an app update. I've used greenfly and Amplify to lock everything down and it seems to work. Its at 52 and charging ATM. Until I did that I couldn't use the phone and charge at the same time

I just changed ROMs altogether, even after wiping I was still getting ridiculous temperature gains, more worryingly so for my battery. I remembered during winter to keep the phone cool I added adhesive copper to the battery and CPU, I applied thermal paste and made the copper thicker, I also *removed* the copper from the battery, since during summer time it'll only make things worse. That seemed to have worked since my battery isn't anywhere near as hot anymore. The CPU still gets very hot - around 80° still, but it seems to level out much quicker than before.

Question Overheating

Has anyone experienced the phone getting hot on the bottom area? Even casual usage such as scrolling through social media makes the phone kinda hot.
I included this picture to show where the area which gets hot first. I only noticed it recently.
Edit: I know the phone has overheating issues but I got concerned how it heats up in the bottom part first since the cpu is no the upper part of the phone, hence something else must be causing the heating issue

I don't really know. Does it happen to you too?

Do you experience any unusual battery drainage?
I'm no expert, but judging by your description, you should check what part of the board is there and what could possibly be making the heat.
From what I've read online, a batch of the phones is faulty and has **** cooling so it's basically a lottery.
On mine, there is no overheating even when playing GRID Autosport for an hour.

No not really, no unusual battery drain. If its on standby for the entire night, I'd lose around 4-7%. Fast charging still works and even has the decimals for the charging pop up. Im not really sure but what I heard is that the phone has a faulty IC that's why I'm concerned. Normally the part that would get hot would be the top part as it is where the processor is. But on the bottom, it's the charging port. It tends to get hotter down there first.

Is it hot like all the time or only when charging? Dang I'd be worried too!
Edit: If I were you, I'd open it up and try to figure it out. Maybe try to run it in battery saving mode to see if that helps?

Its normal, i guess? Because yes my phone also heat up but only when playing game or charging!

A friend of mine told me to format my phone and I did. I don't know why but it kinda solved the problem. The bottom part doesn't overheat as much now. I also updated to the 12.5.5 build of global version.

i also got overheating issue but that because i used custom karnel with MIUI EU 12.5.5, well it is because the custom karnel not compatible with MIUI and will cause overheating. So i just flash back the stock karnel and its return to normal no overheating problem phone cool af and playing games not heating phone that much.

Question Battery Life

I am interested in this battery performance? What SOT are you getting? What do you get for battery time the medium power saver mode?
Any screen shots are appreciated.

It's on Friday and I feel like the first 48 hours it was draining pretty quick. I upgraded from the OnePlus 6t and I certainly feel the slower charge.
Waiting for it to fully discharge and then I'm going to give it a full charge and then I will post my battery stats after seeing how long it lasts.

Full charge before bed last night .. and I drove around a bit today with it plugged in for about 30 minutes. Going to bed now at around 50%. Not going to charge until tomorrow.

I am still trying to figure out if I have a battery drain issue. I am getting the same usage as what I did as my A70. After full charge it says it will last around 22 hours. Usage is the same as with my A70, not sure if that is right.

Standby uses about 1% for every two hours for me with Always On Display. That is always my benchmark even for my last Samsung. There's something using battery wildly if it goes too high after some many hours or even within one hour.
A hint there, try rebooting 3 times in an hour or so. My last Samsung had an issue where normally one reboot would fix the battery drain but it would every now and then require two more to fix the drain.
The battery use stats might help you narrow down to something but if not then you have to factory reset or disable or remove stuff. If its with the rom then it gets more difficult.
If you are seeing the 1% standby for even an hour or two then it should be fine there and the drain is only while the screen is on.
You might also be able to spot certain things the the logcat.

Thank you for your reply. I will try to reboot it. I have done a factory reset but it hasn't helped. I will test it for a few days.

I have 9hours Screen On Time on a pixel experience rom.
AOSP does wonders to this device.

You never know. Funny how much reboots fix things that shouldn't need fixing in the first place
