[Q] Battery drain & Power off problem

I recently bought Samsung Focus from eBay. It has two problems. First, its battery has huge drain. It don't even last for a day. Secondly, there's problem with power functionality. Whenever I power it off it automatically reboots itself instead of powering off. I did hard reset as well but the problems are still there.

You might want to explain a couple of more details like if you are trying to power the focus off while charging it will turn right back on. Also, you can try the official roms located in the in the development section and reflash the rom. In the about section what version of wp7 are you running ie. nodo, pre nodo, mango beta. Also, did you do a full reset in the settings section, through the diagnosis app? You might want to try a full recovery through the diagnosis app. Instructions are in the diagnosis codes thread stickied in the Focus general section.

Also would be helpful if you gave a few details about the condition. New? Used?
I'm going to guess used.
The original owner may have improperly charged the battery all the time. Solution? Buy a new battery. They're pretty cheap. Be sure to look for Samsung Galaxy S batteries as well, since they're the same batteries as the Focus.

If it were me, I would start by flashing the original ROM on the website... you never know what the original owner did, maybe he/she improperly tried to hack the phone and did something.
After flashing so you know you are dealing with a fresh install I would disable wireless/Bluetooth if you do not use them regularly, I would then suggest getting a new battery as already stated.

It's used phone. It becomes warm even in sleep mode. I guess it keeps on consuming battery. And instead of powering off it reboots, even if not plugged to charger or pc.
I think you guys are right; I should try reflashing it. But I never did this thing before. Will it go back to original state, like when it was locked to at&t?

The reboot instead of power off isn't normal.
I can think of 2 things to try:
- Find someone with a Focus and try their battery in your phone (also your battery in theirs)
- Reflash
I can vouch it will stay unlocked, the flash doesn't affect NCK (network lock) - I had to do the same as you
GL and I hope it's not hardware.

Thanks guys for you guidance, but unfortunately even after reflashing I still have those issues.
I used "Samsung i917 Focus firmware UCJK2 AT&T USA" to reflash my phone. The phone has gone back to 7004 state but the problems are still there.
Do you think I should do reflashing with "Samsung i917 Focus firmware UCJK3 ATT USA 4K" this time?
I'm going to buy new battery to see if the new one works. But what do you think, is problem with powering functionality?
Thanks.

I think you should try to go warranty on this. If the board/power adapter assembly is bad, you would just waste more money on this by buying another battery. That's why I suggested find someone to swap batteries for a day.
Reflashing with another Rom isn't going to change much and will just take more time, as this is clearly a hardware issue, this is clear by now.
Maybe drop in a AT&T store and ask for some help? They might know this issue and provide more help...

[Q] Nexus 7 wont turn on or Charge

I have read all articles on this forum regarding all issues but none seems to have been of any help. My nexus isnt powering up. When i Plug it in to power, it doesnt show any sign of charging but the back gets warm indicating that power is actually going in. I have tried long pressing for over 1minutes and still the same thing. No response of any sort. I was hoping there should be something that can b done to it like re-running the os like i did my LG optimus when it had the same issue. Please i need help. I have tried all the options of pressing on the site and none seems to help.

I even changed the battery to a fully charged one and its still the same thing. Since day one it never came on. I have long press for over 2minutes and still nothing. Is there any other thing i can try cus i can send it back to google as my aunt got it for me when she travelled to USA some weeks back and any chance of returning is zero

Phone froze and now will not turn on?

When it rains it pours. In a previous thread I explained how my phone would not boot up. I ended up successfully doing a firmware upgrade through kies which erased everything and brought me back to kit kat.
I was downloading all my apps again in the play store when the phone froze. After waiting a few minutes I did a battery pull. The phone will not turn back on now. My battery was at 80% when it froze. I tried plugging it in and no lights come on. I have held the power button for over a minute and nothing. I tried holding power, home and volume up and nothing. I tried plugging it in the cpu and nothing. I have also left it alone to maybe cool down for a while and nothing.
I'm having a bad phone day and hope someone can help. Thanks.

I think your phone maybe faulty you should take it back to the retailer for a replacement if possible.

The same thing has happened to me as well, but this isn't the first issue that I've had with this phone nor is this the first phone that i have had issues with. I truly think there is a much bigger problem then we are aware of and it has nothing to do with the phone owners. I think there is something wrong with the phone itself; now what that is i don't know. But what i do know is that there are thousands of people who are all dealing with one issue or another. Many of those people are just like myself who pay good money for their phones and expect to the quality and service that their money should buy. But it doesn't and in the end it we are the one's who are ultimately paying the price. And i mean that literally.
Something needs to be done about this. I think its time that we the people start to use are voices and speak up. There are issues at hand and at the very least they need to be addressed and fixed. Furthermore it's time that some of the blame is taken off our shoulders and placed on those who are responsible. My email is: [email protected] If you would like to see something be done about this, please email me. I could use your support. Thank you.

Can my Note 4 be saved?

I've got a Note 4 (AT&T SM-N910A) that is having a problem with reboot looping. I've read some of the posts on this issue, but the solutions I've tried so far haven't worked. I'm kind of overwhelmed by the number of posts on this issue and trying to find solutions. I just want to list some of the symptoms I've had and things I've tried, and if anybody can suggest anything else to try I'd really appreciate it.
The phone started rebooting constantly, sometimes it makes to the home screen before rebooting, sometimes it doesn't even make it past the initial Samsung logo.
It rapidly got worse, the phone was completely locking up during various phases of booting up.
Plugging it into the charger doesn't help.
Completely drained and then charged the battery, didn't help.
Removed the microSD and SIM cards.
I just got a new battery, which didn't solve the problem, but improved so at least it is no longer locking up during the boot process.
Booted in safe mode, didn't improve.
I put the phone in the freezer for a couple of hours. This gave me enough time to install Wake Lock and enable the PARTIAL_WAKE_LOCK mode.
After the freezer and wake lock, I had maybe 5 minutes to transfer some files from internal storage before the reboot started up again.
I can get into recovery mode, where it seems stable, but I don't know if that can help me at all.
At this point I'm only hoping to recover some files from internal storage, then it's time to be done with this phone. Kind of sad that a smartphone that was an $800+ "flagship" barely lasts two years. Thanks

You probably have hardware that is failing (most likely the memory chips on the motherboard). On any of the reboots have you seen a screen like this: http://thedroidguy.com/2015/12/could-not-do-normal-boot-mmc_read-failed-error-on-galaxy-note-4-1052795 ? I've been told that the "ddi : mmc_read failed" message is an indication that the memory chips on the memory board are failing.
It's probably time to contact Samsung Customer Support (1-800-SAMSUNG). That's what I finally did and they repaired my Verizon Note 4 for $70.31 to "like new" condition. See my post here: https://forum.xda-developers.com/showpost.php?p=71863607&postcount=310.
Your mileage may vary, however. Someone else took the same approach and it is going to cost them more. See post here: https://forum.xda-developers.com/showpost.php?p=72258958&postcount=313. You don't have to agree to Samsung's repair estimate if you think it is too high. My understanding is that if you refuse they will send the phone back for no charge. Before I sent mine in I had mentally set an upper repair limit of $150 since you can still buy new Verizon Note 4's on Amazon for about $300.
Good luck.

Hey thanks for your input. I haven't seen any kind of error screens pop up. $70 to have your phone reconditioned is a really good score for you. I was able to pull my phone from the freezer several times and at least got all of my photos and videos off, which was my primary goal.

LG randomly overheating and won't stay on - No previous heat issues

Hi, I have a LG K20 Plus. I currently can't turn the phone on, so I don't have much software information to give you. The phone was bought at T-Mobile (Metro by T-Mobile) and I had a SafeLink sim card and a 16 gb micro sd card inserted when the issue started. I have since removed both. It says Qualcomm snapdragon on the screen when it starts. It was also rooted and the bootloader is unlocked.
I broke the screen on my phone and I decided to do the repair myself. I have done about 7 or 8 screen replacements and I actually did this phone a year ago with no issues, so I felt I could manage this one as well. I bought an entire display (from ebay) and switched it out with no problems. Initially it worked great! I used it for a few days before realizing that I had no sound. I opened it back up and noticed the loud speaker had fallen out. I found it, put it back in, reassembled it as I normally do and turned it on.
NOTE: when I was reassembling it the second time, I actually tried to put a screw in a hole that wasn't a screw hole. I used a light to normal amount of pressure but I didn't force it. I think it's the hole where the moisture detector is. Picture #1
I turned it on and right after the logo screen I got a message that said "High temperature detected Powering off for your safety" and it immediately shut off. The phone does appear to charge normally but it won't stay on. I did a factory reset (I'm not sure if it's still rooted but the bootloader is still unlocked). I also switched back to the old (broken) display just to check if that would work. I couldn't see any difference in the shielding but I switched them just to be sure. I bought a new battery and installed it. I took a q-tip and 95% Isopropyl Alcohol and cleaned pretty much the entire motherboard, paying special attention to the battery connections. After each one of these things, I tried to start it with the same error message immediately upon start up.
NOTE: At no point has the phone every physically felt hot or even warm. I don't think it's on long enough for it to get hot. But something is wrong and I have no idea what it is. I, literally, took the phone apart, put in the speaker and put it back together in less than 5 minutes. Could it be I just bumped something and knocked it loose?
I searched for any information I could find both here and with google but there is next to no information on the LG K20 Plus. I did find some information on the LG V20 that had overheating issues, and that has been all the luck I've had. I watched several videos and it seems the solution is to apply thermal paste. But my phone doesn't have any evidence that thermal paste was ever on it. I went and bought some but I have no idea where exactly to put it or even if it's needed. Most videos showed people using some kind of aluminum foil but I'm not sure if that is safe. I have several old phone laying around and I managed to get some of the silver tape and a copper square thing but, again, my phone did not have these things to begin with. I don't want to start adding things only to make it worse.
There is a slight difference of the tape that is on my phone now (the display I just bought) as compared to the old one (broken display). Picture #2 Again, I have no idea if that means anything but I thought it worth mentioning. Picture #3 is how it looks now as if I were going to put it back together. Picture #4 is the part (don't know name) where the videos show to apply the thermal paste and the shielding.
I'm really at a loss as to what to do next and I can't really afford to take it in to have it repaired before next month. If anybody has any insight or answers as to what happened, I'd be very grateful for your help. I'm sorry for the long post. I just wanted to tell you everything I have done in detail. Thank you

If you're using Kernel Auditor or any other kernel adjustment simply reset to default and use only ondemand or interactive. There's also options for the thermal portion of the kernel, don't mess with those. If VCC or another thermal option was checked off turn it back on. Putting the GPS to the moderate setting (the one below high accuracy) will keep the temps down as well. Are you using a custom ROM? If you're on Discord you can feel free to message me SCOPE★ BRΞΛD #8460 . I am only offering that so we can get this resolved quickly for you, just copy and paste since I use special characters.

Omgosh, thank you so much for taking the time to respond! Although I'm sure everything you are saying is very smart, I have absolutely no idea what you're saying. I'll do my best to try and answer you. I don't know what SCOPE is or how to send a message there. I don't think I'm using any thing for the "kernal". Also, I don't know what VCC or Discord is. As far as turning off setting for GPS or any other app, the phone will not stay on. I get about 1 sec after the logo when it boots up, then the error message about overheating and it immediately shuts off. I did a factory reset so everything should be good to go as far as apps. I don't think I'm using a custom ROM. The only thing I did was install TWRP, unlocked the bootloader and rooted the phone a year ago but nothing since then. As I stated earlier, this happened right after I did a display repair. Is there something on the MOBO that can get bumped that will make your phone get hot or send a overheating error. My phone doesn't show any sign that there was ever thermal paste on it prior but should I add some now. Will that help?

Update... Now the phone does not power on at all. When I plug it in to charge it I get an error that says "Device temperature is too high or low. Please move to another place to charge. I wonder where you went. I googled SCOPE so I could sign up to message you like you asked me to but nothing but definitions came up. I know I'm out of my league here. You guys all talk so technical. I didn't understand one thing the person asked me for. I know it's rare to get a response as quickly as I did and I was so happy to see someone had responded. Now, I just feel stupid and defeated. I thought this site was inexperienced with cell phones friendly. I'm just trying to get help so I don't have to go out and buy another phone again. Can someone refer me to a site that is more directed toward people who don't know much about the technical side of cell phones... please! Again, thank you for your time.

Hey, I just wanted to say sorry this happened to you. The same thing happened to me. My LG K20 Plus, no matter what button combinations I push and for how long I hold them, will not turn on or go into download mode. Plugging it in to a charger or PC does nothing either. Before it got to this state, I got the infamous green screen of death/Demigod crash handler (google this--it's a known issue with some models of LG phones and it happens when they overheat). It's definitely a hardware/build issue, and especially since this issue keeps the phone from turning on or connecting to a computer, I don't see a workable fix short of buying a new phone, unfortunately. Again, I'm in the same boat so I'm not happy about it either. I would say XDA is by far the best site to find a fix to this sort of problem, so if no one here has any suggestions on how to fix it, I think you (we) may be out of luck.

Thank you for letting me know. I'm not sure of some of what you said but I did catch the bottom line. Basically, just hold onto the phone until someone here comes up with a fix or workaround? I have a question for you. Did your problem start after you did some kind of repair? I'm wondering if I bumped something on the mobo to make it give a false overheating error. Do you happen to know where that sensor might be located? Sorry you are having problems to. It really stinks when your phone breaks and no matter how much time and energy you put it to figuring out the problem to fix it, there just isn't any good answers out there. I wish you lots of luck and if you figure anything out, please update here so I can try it too.

You need a whole new phone.
That or you're gonna have to replace the hardware
