Hi guys, i had my xperia ion at charge after my battery went fully drained. But there was some electricity workers doing something on the electrical pannel on my street... i think that they have closed and opened the electricity several times. Now my phone is shuted down ... the only think he does is that when i put it to charge the red led turns on but after a while it turns off ... i can't start it. Does any one have any ideea how i can turn it back on? Thank you and sorry for my english.
No one knows?
Not sure if this helps but in this threat

under Battery Charging Cycles is following information:
On a working phone there are different stages of a battery's charging cycle. The stages are listed in order they happen. The cycle goes from a completely dead battery through a phone running on battery and back to a completely dead battery.
Dead battery. No response from the power button, no screen and no led.
Connect to charger
low battery level charging mode. This is when just the RED led is on and no screen. At this stage the battery's charge is to low to turn the phone on, but it is charging.
Kernel controlled off-line charging mode. This is when the battery has charged enough from step (3) and boots the kernel to charge the battery. The phone is off, but could be turned on using the power button. A quick press of the power button will show this battery icon. Icon will fill with charge.
The kernel also controls charging when the phone is on.
Battery is fully charged.
Unplug the phone and turn on.
Battery is dead from normal use.
Repeat stages starting at (1)

Does anyone have a link for the thread that discussed the correct way to wipe battery stats when upgrading to a new Rom? I remember it went something like drain dead, charge to full, drain dead again then charge to full and wipe stats. I can't remember the complete process. Thanks for the help.
Sent from my PC36100 using XDA App
I've seen a couple different threads on that here, one saying discharge fully then charge while powered off, and the other saying to do a full charge "conditioning cycle". I did the latter and it seems to have made a difference.
Here's what I did:
Charge the phone fully with it powered on
When fully charged, disconnect cable
After green LED goes off, power the phone off
When phone is fully powered off, reconnect cable, amber charging light should be on
When LED goes green, disconnect cable
Repeat previous two steps 10 times
After 10th cycle, boot into recovery and wipe battery stats.
I am using Amon Ra recovery which has the wipe battery stats option under the Wipe option. I never did this when I had Clockwork recovery installed, so I don't know if the option is in the same place.
Being an electrical engineer, I find this business of battery conditioning interesting, along with the Ni-Cd "memory" vs. Li-Ion "no memory" issue. If anyone has found a decent physics-based explanation as to why these things do or do not have any basis in fact, I'd appreciate a link. Yes, I'm too lazy to Google it at the moment.
Hmm, I may have to look into this again. I charged my phone all night (powered off) and unplugged it this morning. I did nothing with it this morning but turn it on and look at it, then put it in standby (quick press of power button). It lost 16% of charge in less than 2 hours!
I'm running BS1.2 with the Baked1 (low voltage/best battery) kernel.
Damn, just installed System Panel and found that my CPU is at 100% constantly!
I'm trying this now. The longest I've pushed my battery was 22 hours... and that was with 39 minutes of screen on time, lol. In standby almost the entire 22 hours....
Ok, I believe my issue was related to a camcorder problem, my CPU usage has dropped back to normal levels after fixing that separate problem. After my battery recharges fully I will see what happens with the charge.
the other methods to do "calibrate your battery" (which isnt really calibrating the battery but the battery stats of the phone so it can accuratly judge when it stops and starts charging)
1) charge the phone to full
2) unplug and use phone till it shuts off from no battery (do not plug in until it shuts off)
3) charge phone to full again with out unplugging till 100% (check under about phone > battery it shoudl say full charge there)
this should reset the battery stats.
the last method is one from HTC
1)Charge the phone for 8 hours uninterupted with power on
2) turn off the phone and charge for an additional hour
3) turn ont he phone unplug it and let it sit for 2 minutes then plug it in for an additional hour.
all 3 methods listed should help. I personally dont like the x10 method because it has the potential and basically over charges the battery to make sure it is acctually at a full charge. It is much faster then the other 2 methods though so to each there own.
Dont waste your time on...
plug/unplug 10 times. It really doesn't recal the battery.
the unplug/plug 10 times.
1. Phone on...charge until green light comes on. Immediately unplug and turn phone off.
2. Plug phone back in until green light comes on again. Immediately boot into Recovery and wipe battery stats.
3. Use the phone on battery until dies.
4. recharge phone to 100%
You are good to go!
If I tether during the day (5+ hours) a lot, is it bad on my battery? Isn't that like a constant charge or does once the LED turn green it stops trying to charge?
Thanks.

the evo doesnt do a trickle charge so when the light turns green it stops, this is why you will almost always drop 1-5% battery rather quickly.
Are you sure? My light has been green for a while, and my phone battery status says 'Full'.

There's a lot of confusion over how the battery / charging circuit works and how it reports. My advice is to just charge until it's green and full, then unplug it. If you leave it plugged in all night, unplug it for 10 mins in the morning, then plug it back in to top off.
That doesn't really help me SilverZero, my question is only if leaving it tethered (which means connected to USB) is bad for my battery.
Well on mine i would check it every once in awhile and i would see that once it get downs to under 90% that it would charge again till it recognized that it was full again. So based on that i dont think you should have to worry about it. It seems to only draw the charge when needed. I also leave mine plugged in alot when im home so its good to go when i leave and havent noticed a loss of battery life at all.
You guys don't want the charger to trickle charge. Li-Ion does not accept overcharge, even 0.01C (15 mA on the stock Evo battery) will cause it to vent and probably combust.
So does "calibrating the battery" calibrate the phone or the actual battery?
I ask because I have 3 spare batteries, wondering if I have to do this for each of them??? They are all standard size, one of them OEM
When the power is on the TP2 the red LED charge light is on. the icon in the task bar changes to show that it is plugged in. but after sitting for hours the battery only drains further. If i power the TP2 down plug it up the red LED comes on and the battery charges fully to 100% then goes to green. I have bought new battery and charger. any ideas? note it is allowed to charge via usb in the settings. thanks folks
This is NOT a issue. It's a feature.
Phone does charge to 100%, but later the electricity is cut off until it reaches ~95% (or something like that). It prevents the battery from overcharging and saves important battery lifetime cycles. If it would be charged constantly from 99% to 100% the battery would be dead in a month.
ok so i got a problem with my battery
my battery on my phone just going out to fast
for example today
i connected it so it could reload and then
when i disconnected it was 100%
then after 2 hours only that i havnt use the phone i mean havnt touched it even once
i look again on battery life and here it says 36%
and it keep going every day
can some1 tell me why it keep happening???
WOW! That's a major drain in 2hours.
My 2 cents are on a defective battery - since the phone was on standby.
You can try some tutorials on adjusting the power saving settings (like screen brithgness what to turn off and not etc.)
Also you might try caibrate the battery.
there is a thing like u charge it to 100% ,unplug from the charger and turn the phone off ,then plug in again and charge to 100% again... there is a thread about it on this forum, do a lil search it might help u
Dial *#*#4636#*#* and go to battery and find partial wake usage, here the apps are listed that prevent the phone form sleeping and thus causing battery drain. Also check the % under Settings-about phone- battery usage to see what app or process consumed the most battery.
Does it get very hot? I mean - if the battery really contains 1500mAh (which I doubt in this case) and drains completely in 3 hours, that's 500mAh, so 3.5V*0,5A=1,75W continuesly.
You really should notice that while it's in your pocket...
no the phone isnt getting hot
i mean it can sit on my pocket for like 2-3 hours and then it suddenly 3x %
without even touching it
Try these steps:
1. Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged.
2. Disconnect the phone from the charger, and power it off.
3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green.
4. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green.
5. Disconnect the phone, power it on (OPTIONAL: Enter Recovery at this point and Wipe Battery Stats (from Advanced menu), and use it. You need to use this sequence only once.
If that does not solve it you have a defective batterie.
ok i will try it
but can u tell me what the point???
i mean what does it do??

The point of that, is to make the battery life longer. And actually it works. I tried when i bought my phone an the increase was significant!
Edit: Just saw in another thread that some newer custom ROMs has some things messed up, and they eat the battery more than normal when the screen is off. You might take a look at it.
yea i did all the steps and its not working
the battery still going down rapidly
so i should buy new one??
Yeah.
BTW, are you on a stock rom?
srry
no idea what stock rom means
but im on miui rom
Since i was having problems with the battery levels i thought to run the battery dry, but i noticed that the phone was not shutting down on itself ?? it kept running on 0% and voltage decreased to 3068mV ?? (isn't that way to low ?)
I tried to power it off and on again, but it didn't boot. So i put the phone on the charger and the orange led kept blinking (1sec on, 1 sec off)??
Eventually i held down the power button and then it started to charge and i could boot again.
But what's the problem with my phone ? shouldn't it shutdown @ 0% battery on itself to prevent battery damage?

same here mate suddenly the screen went off without any warning but no it did shut down but maybe not proper software shut down, since when it regained power i had fast boot off so the phone booted from the start, the power was not @ 0% when it went out, so i dont think there is a worry about hardware or battery
yea i guess one of the many bugs, its a beast that needs to be tammed
I just drained my battery to 0 and it shut down. Now when I put the charger in there is no LED, and it doesn't turn on...... what do i do??
I am on a custom ROM. Does this mean it won't charge now because the recovery doesn't support it?
Edit: eventually the red LED blinked, then after a few minutes it stayed on solid. Then I was able to turn it on.
I have a odd problem. I have the Leedroid custom rom with its kernel installed, and it seems as when i plug in the charger that the battery DRAINS extra fast instead of CHARGE. I have no idea whats going on. The red LED light is on as usual but when i turn my phone off for a while and let it charge and then turn it on i only had like 5% battery left when i started charging at 20%. What do i do? Is this some kind of bug?
I dont believe that i cannot charge my phone, but im afraid that if i leave the charger in my phone will become completely drained of battery and that i then wont have any option left.
Please help me, my phone only have 5% battery left, and if there is something i can do before the battery drains completely, tell me as fast as you can!
Thanks!

Never mind, i got it to work. It seems as if the battery didnt get enough electricity. Probably because i got the charger hooked up to a powerstrip whom also have a halogene spotlight connected to. That was on. The phone died and when i tried to charge it the red light flashed. So i turned off my spotligt and tried bashing the powerbutton.
The LED started to statically glow red and the phone turned on. I almost panicked because i rooted the phone yesterday and have only had the phone for like 1 and a half week.:angel:

why dont power off the phone and charge it. maybe there are apps that cause it

why dont you check which apps consume the battery.

In this case it wouldnt have mattered since i charged the phone while it was turned off, but as i just wrote, i found out what the problem was. Haha :laugh:
So, a moderator can close the thread if he/she would like to. I will change the topic to *SOLVED*
