I gave my phone for repair to Sony, got it after 1.5 months. They said my battery is too low, so gave me another one just to check if the phone is working properly. I came home back, and the phone has been on charge for 2 hrs but it is not yet turning on, with LED continuously blinking red. After some research, I think that the reason is phone won't allow the battery to charge as it has drained to zero, and I need to jump start it by charging externally. But I don't have an external charger. I don't want to approach stupid Sony customer care again as I have had enough of them. Someone please help.:crying:
Have you checked the battery slot? Maybe its not reading/connecting properly... Try cleaning it up. Or leave battery out for a few minutes.

Have searched the forum to death regarding this and tried everything. The battery slot seems fine. Either Sony has damaged my phone's charging circuitry, or the problem is the complete battery drain. Do I need to charge the phone for several more hours? Is the battery now unusable after draining to zero?

Get a USB cable that you dont need and cut the mini end off to expose the wires. Plug the big end into a charging source (either PC or wall charger). Take the battery out of your phone and hold the red wire to the positive and the black to the negative( the battery terminals are marked), you will have to do this for at least 15 minutes or if you can use sellotape or blu tack for a longer period. This will hopefully put enough charge into the battery so that when it is reinserted into the phone it will be able to charge it normally. This is a common android problem.

Thanks infinite times, you r genius, that was the solution I was looking for. You saved me another trip to stupid Sony customer care. It is funny that despite these days of sophisticated technology, I had to resort to such primitive method for charging just because of the lazy manufacturers who want everything done by the readymade OS and cannot put in some extra hardware to overcome a serious and obvious defect. Thanks again.:good:
Your mother board might have a short. My previous phone have this issue and I had to use another Play to charge the battery. It also had battery drainage over night. I would recommend getting an external charger and extra battery, they're fairly cheap.

Hi everyone. New here so I look to you for answers. I bought my HD2 about 2 weeks after they came out. Used it for about a month and started using a couple different phones for a while. My HD2 sat on my desk with the battery out of it for about 3 months before I decided to use it again last night. Last night I plug it in to charge and no charging light and it wouldn't turn on. I let it sit all night and still nothing in the morning. I took it to the t-mobile store and they tried a different battery and charger and still nothing. They suggested to call customer service since it is still under warranty. I have not flashed any ROMs or or changed it from stock in any way. Any suggestions before I go the customer service route? I searched the forums and could not find any answers to my specific issue. I appreciate any help you guys can give me. Thanks!
What kind of charger are you using? It sounds like your battery is completely dead, and to get it to charge you MUST use a charger that outputs 1amp. The stock charger provides this, but most 3rd party ones don't. Try using the stock charger for a couple of hours, and if that doesn't work, you will probobly need to jump start your battery using a common 9-volt battery. If it comes down to that let me know and I can walk you through the process.
I used the stock charger that was packaged with the phone. I think you are right that it is completely dead. How would I go about jump starting it? Thanks again!
Its fairly simple really. You need a 9 volt battery, and 2 peices of wire. Simply attach one end of each wire to the 9 volt somehow(tape, wrap the ends around it etc...) and then put the other ends of the wires to positive and negative on your HTC battery, observing positive 9 volt to positive HTC battery of course. You will more than likely have to hold the wires to the HTC battery, which is fine, just dont let them touch each other or you will risk shorting out and/or bursting your 9 volt. Anywho, hold them there for 2-5 minutes. If your HTC battery begins to get warm STOP immediately, let it cool down, then put it back into your HD2 and charge it with the stock charger. While the 9 volt battery doesnt supply as much amperage as the charger, it does provide more volts of course(9-ish versus 5) and can cause the battery to overheat and in some cases melt. After no more than 5 minutes, your battery should have 2-3% of a charge, which is enough for it to be recognized by the phone, and enough for it to be charged by the wall charger. The overcharge preventing circuitry is the reason why you sometimes have to do this trick, if the battery becomes completely discharged(less than 0% power) the overcharge circuitry recognizes it as being fully charged, or faulty and therefore will not supply it with power. Try that, and see what happens! And if nothing does, let me know and I will tell yah the next step.
Worked perfectly. Thanks so much for your help. I knew I'd find the answer on XDA.
No problem friend, glad I could help you get it back up and running!

I recently let my phone go to 0% battery because i forgot to charge it last night. This is the 1st time this has happened. So i start to charge it & it still doesnt turn on. The LED flashes orange & green on ear grill. any suggestions ?
Pop out the battery and plug it back in a wait 5 minutes. If its still flashing like that (green and orange) that's a charging error. One of two things... bad battery or bad charger. Of course check a different outlet too. Happened to me before with a bad battery... flashed green and orange. Switched batteries and all was good. Good luck!

Thanks. My friends at school has the same phone as me. So i will try his battery. If that works I will sure to thank you
the phone shuts off before the battery can be damaged. just let it charge a while.
so hows the outcome? *curious*

Not always true. The safety circuit on the battery is supposed to prevent over-discharge. But its possible if you drain the battery drain to zero, and the safety circuit does not work properly (doesn't happen often, but it does happen), that the battery will be over-discharged and no longer be able to take a charge. In this case, only a special battery meter/charger with a boost function will bring it back to life.
Slight chance that the following will work: plug the phone into the wall charger (not USB) and leave it overnight. Then try to power on. Otherwise, you may need a new battery.
This is why you shouldn't let your battery drain to zero. I understand if it was an accident (happens to all of us once in a while). But some people let their battery go to zero intentionally, which is not wise.
Guys i figured out what the problem was. Some how the battery touched water & if you take out your battery & look at little white sticker. If that turns red that means it touched watcher & no longer works... Figured that out today because my friend has the same phone as me & tried his battery. So i will be buying a replacement battery ASAP.

My understanding that lithium ion batteries cannot recover if totally dead. Therefore, a battery at 0% is more like 5% and are built that way as a safety measure.

Hmmm... interesting! No good for you but facinating nonetheless, lol! You could try lightly scrubbing the battery contacts with alcohol and old toothbrush and let that baby dry out for a week. I bet it starts working again... it'll will be a nice backup for ya!

I think that is true. But over-discharge means that the battery still has some charge, but too low for it to take a charge from a standard charger. Then, only a battery meter with a boost function will bring it back. The safety circuit is designed to prevent it from going below whatever the "over discharge" threshold is, but its not 100% reliable. I've seen several reports by XDA users for the Desire Z/G2 what have killed their batteries by running them to "zero", and similar reports on past HTC phones I've owned and followed on these forums.
I am having problems with my Nexus 4.
History, replaced screen after phone was knocked out of my hand, probably damaged battery while trying to remove it, but everything worked once it was back together.
Screen broke again, and while working on that, I noticed the battery had swollen so ordered a replacement of eBay.
All back together now, but.
1 Phone does not state "charging" when connected to AC or USB charging, although the battery icon has the lightning bolt in it and the %charge does not drop while messing with the phone.
2 Phone does charge using wireless, but slowly, and status swaps back and forth between charging and not charging and the % will move from e.g. 40% to 35% as it says charging or not charging.
3 USB works for connection to PC.
I charged the new battery overnight, wirelessly. It got to about 90%, so slow charging, but seems to work. Phone is usable, everything seems to work. I connected it to PC and was able to use Nexus Root Toolkit to backup, the reset the phone, no change in charging behavior.
Booting into safe mode made no difference either. So it seems it is not software/firmware/apps that are causing the problem?
I guess next step is to open it up again and remove and remake all connections and check contact posts? Should I order a third battery? Or a new motherboard?
I searched here, but could not find anyone with the same problem.
Any and all help appreciated. Thanks in advance, guys.
Opening and rechecking connections and coating with contact cleaner has made no difference.
Phone typically needs Volume Down and Power button pressed to get it to start, then Power Button to select start option, then seems to run okay.
Battery still not reaching 100% charged, generally 70-80% after a full night off, using wireless (my Nexus 5 charges happily on same charger).
Ordered a cheap battery from China, not really expecting that to be the problem, but no other clues or suggestions for now.
Any update?
My battery is ****e now, lasts 3-4 hours and I need to turn off the phone and charge. It takes 4+ hours to charge when switched on. Charging via the PC you can forget it, it drains the battery if anything!
I'm thinking of buying the battery on eBay and doing my research on how to fix myself.
Phone not switching on and Battery issues
Hi,
I have been facing quick drainage of my Nexus 4 battery since past few months. Recently I had been keeping it on charge almost the whole day, and a full charge would last only 2-3 hours! Further, the charging was taking a lot of time too.
Today, my phone had already switched off due to low battery when I put it on charger. After the white charging icon appeared for a few seconds, the phone wasn't charging at all. I have tried 4 different chargers, but to no avail.
Can someone help me? Is there a guide on how to change the battery?
Any help and urgent help appreciated!
Zany!

It's possible some hardware was damaged when you took apart and put back together your phone. The USB board is a possibility, as is the back cover itself. These parts are pretty inexpensive, if you want to try buying a replacement, but that's just a shot in the dark.

Buy a new battery. Li-ion batteries are only good for a few hundred cycles or so (~500 cycles is the expected lifetime), and the N4 isn't exactly the best in battery life, so you can reach the point where your battery turns to crap within a year or so (or less).
Go to ifixit.com and look at the teardown. All you need to replace the battery is a T5 TORX driver (for the screws at the bottom), something thin and plastic (like a guitar pick or a plastic knife - they do make professional tools for this) to pry the back cover off, a tiny phillips screwdriver (like for eyeglasses) for the battery screws, and something to pry the old battery off of the adhesive holding it in. Double sided cellophane tape works fine for keeping the new battery in. When prying the cover off, go slowly. A little at a time, don't rush or force things. Or you might flex too much and crack the back glass. Don't forget to take out the SIM tray first.

Time for a new battery. See above.
My battery have started to swollen up a bit but not alot (around 1mm or less, but it is noticeable when not in a case, it can wiggle a bit from side to side but not alot at all).
I have already ordered a new battery if it is expanding more, but yet battery life is pretty good in standby but not getting more then 3hours of SOT. but since im mostly using the N4 for email's and texting its not a problem for me to get through a full day.
I'm having the exact same issue but I've never taken the phone apart. In the 20 minutes its been off charger it's dropped 11% screen off in my pocket. It also gets hot and shuts off.

That could be software/ROM related. It sounds like somethings keeping your phone going full blast instead of letting it idle.
Yup, trying going back to full stock (should always be first step if possible), and then you can go from there. If it doesn't happen, than it was a software issue, and if it still does than it is definitely a hardware issue. Best of luck.

With a swollen battery I strongly recommend you stop actively using the device. Swollen batteries can explode and that would not be good at all. I advise you to please not use the device anymore.

Third battery (original, suspect replacement, now China sourced replacement) has been working well, phone back together and preforming as new for the last few months
Hi guys.
My Defy switches on only when plugged in. If I remove the charger it suddenly switches off. Any idea what may be the problem?
Sounds like a defective battery. Do you have a spare one to verify?
Of cause it can also be a lot of things sourrounding the charging circuit. If it is defective the battery will be drained at some point without being defecive itself.
---------- Post added at 02:31 PM ---------- Previous post was at 02:26 PM ----------
Come to think of it this could also be caused by a defective usb-port (on the phone). Can you turn the phone on at all, when it's not connected to the usb-cable?
Thanks a lot !
It was the defective battery. Tried my old battery and it works!. But this is the old battery with capacity which has decreased a lot..
Can the defective battery be repaired? Looks like a loose connection problem..
Thanks anyway.. :thumbup:
I doubt you'll be able to fix the battery. Usually when a battery dies there is something wrong with the chemestry inside it (like crystilization which leads to a physically expanding battery). I wouldn't bother. Just get a new one. But be aware most of the battery on ebay are fake and don't last nearly as long as an original motorola.

Yes you are right. Also it is not my primary phone now as I have a moto g.
Advice appreciated. I tried every startup option from the web for "dead battery" etc. No success, so I obtained new battery and charger jack. (Connections rechecked)
But it still won't boot.
Is their anything else I can try, or is it for the rubbish bin?

Had the same issue. Got a new battery and it was 66% could not get it past that. I also changed the charger port . Did you make sure the cable connector was pushed down on the top ?. I also sprayed deposit on all connectors. Let it charge powered on for close to 30 hours. It now charges fully and battery seems to last. Still slow to charge but way better using a 2.4 ma charger ... hope this helps.
Screen blank
Desertrider, thanks.
My problem is slightly different. Would not start, had blank black screen, all dead. So I checked all connections, and then ordered new charger jack. Still dead, no charge.
So I ordered new battery (which theoretically should have had residual charge). Still dead, also after several hours of charge.
So I assume this means that some other component in the Nexus has failed, preventing revival of the tablet?
Has anyone similar experience and recommendations?
I have the exact same issue. I've removed the shielding and can feel the battery charging (from poor earth).
Did you get anywhere? I'm tearing my hair out.

HI
I still have nothing. What do you mean by "feel the battery charging (from poor earth)."
Logically, with new battery and new charger jack, the battery should function.
So is it a screen failure issue? I wonder how one can test for this?
regards D
Bzzzz
If it's charging and you have the back cover off, stroke the batter and there is a slight buzzing sensation. Similar to macbooks and iPhones. Since they aren't rather earthed properly, you get a buzzing sensation when touching the metal parts.
I had consider a screen issue. Guess only way is to get a new LCD module? Probably the same price as one of these things second hand now.

Actually, doesn't the Nexus 7 support HDMI out? If so you could connect it to a tv. I have a feeling I may have a converter cable somewhere.
