Hey guys. I have a Micromax Unite 2 8Gb model. I have used it for 3 yrs constantly but then i decided to buy a new phone. So this old phone was off for few months. N now it wont charge or turn on. Any help?
Your battery has suffered a deep discharge.
If you got a multi-meter check lead V on battery
If 1.5 v or less buy new battery
If 2v then charge battery with slow external charger by removing battery from device
Give it at least 5 hrs
Check lead V again. Should be 2.6V or more
Now insert battery in device and charge to 100% before switching on

Hi.....
I am new on XDA.
Need help regarding battery drain issue on Samsung Galaxy I9103. I am using this Smartphone since November 2012 with default stock ROM and found it a good phone. No Root, no custom ROM flashed ever. But recently I faced the battery drain issue, sometimes it is worse. I change the charges as well to assuming that my charger is not charging battery properly but result was same.
I was about to change the battery. But today mobile is delivering outclass performance again which is very surprising for me. Last day I charged my mobile 3 times and every time battery drain out so quickly on idle / stand by mode.
Last night I charged the mobile about 65% and switched off. Then in morning I charged it again while mobile was still switched off and unplug the charges when battery was around +90%.
Question
1. Whats wrong with mobile?
2. Should I change my battery?
3. Any other issue.

the possible reason cld be,
1. some backgrnd process running constantly
2. device not going in to deep sleep when screen is off (requires root to check )
3. cld be a faulty charger or faulty battery in worst case scenario.
but i suspect reason 1 or 2.
if u r not rooted, very liitle v can know the cause of your problem

Hello
Good day.
Please review yesterday performance image. Most important, when I gave nap around 7-8 hours to my mobile, it is delivering good battery backup.
Further I was searching on net to regain Li-Ion batteries for smart phones and got following. Kindly validate this method.
Disclaimer: This should be used only if you believe there’s been an obvious decline in your battery life.
As promised – here is one method for bringing trusty dusty back to life
1) Turn your phone on and charge for 8 hours or more
2) Unplug the phone and turn it off, then and charge for 1 hour
3) Unplug the phone turn it on wait a couple minutes then turn it off and charge for another hour
Your battery life should almost double.
The logic behind this method is that your phone runs on battery power all the time even when its plugged into the charger. One side of the battery gets charged while the other side is keeping the phone on. So…if your phone is on while charging it never gets charged 100%. Doing this once or twice a month should recalibrate the battery and bring it up to full usage.

Dear All
Need your response on above mentioned method to regain the battery life. Plzzzzzzzzzzzzzzz help.
Hi all,
I got my Canvas 2 ( 4 days ago ).
Cheers to this forum & all the awesome devs here!
Since I have bought Can2, I could only get to charge my device upto like 95% or so.. ( some thing or the other kept coming up!! DAMN! )
My phone has been giving like 1.5+ days of backup or so.. ( this is with heavy use - games/Wifi/whatsapping & data on whenever wifi is off ).
My phone came with 4.1.2 out of the box!
No root/flash yet. ( still discovering the default power of the phone ).
But --
Today I observed 2 things:
1. I put the phone on charge - and it just was stuck at 15% for quite some time. the charging red LED was 'blinking' the whole time!
-- this charging was through a multipurpose "Croma" portable charger. ( I was charging it through 2 pin plugged to electricity ).
I am not sure - whether the charging LED should blink or stay lit!?
I restarted the phone - and suddenly battery was like 67% !!
2. I disconnected the charger - and plug the usb into my laptop.
Now - the LED (red) was not blinking - it just stays lit.
But- the charging seems very very slow!
in last 40 mins it has just moved to 73% now.
What's going on?
Right now - I am running busy at work.
How can I handle this problem without "rooting" or anything that requires 'reading'?
Thanks in advance folks!
Sony.

Its ur charger problem.. Change the charger.. And if u charge through computer then it charges very slow because of Amperes. Not to worry. I recommend u to buy a usb adapter of 3Ampere. And charge with it. It charges fast .

Thanks man for the reply!
I used the MMX charger yesterday night ( and was relieved ) to find out that phone is charging 1% per 4 mins or so.
^ which I think is ok.
May be my all purpose charger isn't good enough for this phone.
And yeah - the PC USB charging is painfully slow -- like 1% every 13~15 mins!
Cheers,
Sony.
