I need help with the phone. I have discovery V5, android 4.2.2 Z3Z6Z7W MAUI.11AMD.W11.50.SP....... etc phone where battery life is no longer then 3 hours on standby. I have received 2 batteries and both of them have same life expectancy. When I contacted supplier I bought it from, they agreed to send another battery, but the problem is same even with the 3rd battery. So, I am guessing issue is with the phone but I am hoping it is something to do with the system and it could be fixed with some kind of update. I am not an expert in those things but being into elecltronics for more then 20 yrs, I do have some kind of knowledge, but not enough in this sphere.
Any ideas what could i do and how, please ?

Hi, read a lot of threads about wifi-sharing on the Galaxy S2 and just on Android in general. I have not found an answer for my specific situation. I have NEVER configured, used, or even glanced at any menu settings regarding any wifi-sharing features on my phone. Yet, for the past 2 days my phone battery is all but dead by noon to 1 pm after NO use due to wifi-sharing showing up in battery usage at about 85%! "Media sharing" is showing up too. As I said, I've never used this feature before, It's never even showed up in battery usage before. I have NOT installed any new apps recently. Any ideas why this would be happening all of a sudden?
Paranoid side note : Can wifi-sharing be activated remotely?
For some reason the wifi-sharing only shows up in battery usage after arriving at my workplace. Is there such a thing as someone else remotely turning on your wifi sharing on your phone? I know that the phone carriers have the capability of doing this, but does the average Joe have this capability as well? I also recently became aware that bluetooth can be hacked to get through to your mobile data, that's why I'm wondering about the possibility of remote wifi-sharing activation too.
Somebody please tell me I'm an idiot and there is a perfectly reasonable explanation.
And be nice please. Thanks.

Unless you paired you mobile with any other in your work place its almost unhackable. If you see anything under paired devices in wifi direct , remove those.
Haven't seen this exact issue mentioned elsewhere, apologies if it has been.
Now we have battery stats in .21, I've noticed the biggest drain of my battery when the tablet is in standby is Google Maps. It's slow, but steady and it appears to be the WiFi is being held on constantly. My guess is it's Latitude doing it's updates, but can't be sure yet.
I have Disconnect network during sleep set to True, and Keep Wi-Fi on during sleep set to Never.
I tried changing Latitude's Location Reporting to Do not update your location as I don't really need it on the tablet, but this setting seems to sync with my Android phone, which is where I do want it.
Example of what I'm talking about in the attached screenshots...
Anyone got any thoughts on this?
Very similar problem with my Prime.
I contacted Asus Support about Battery Drain since .21 upgrade and they told me that my Dock has developed a fault and to send back to them.
I know my issue isn't related to the dock, as I don't use it very often
It really seems that only a few people seem to have the wifi battery drain problem after the .21 update.
I think its not related to any apps. I deactivated maps/latitude and I tried a hard reset with standard apps only. Same result. Since the .21 update I only get 6h screen time [previously 11h] and wifi sucks up to 60% of the power.
Really frustrating and ASUS supports proves again useless.
Just want to add, that the support told me that there is a new update on its way. He couldn't give me a precise date, but he said in the next few weeks for the german customers, so I assume within the next two for US/international. He said that issue was adressed.
Since my trust in the words of the support is fairly limited, I would like to know whether there is a possibility to reduce TX Power on wifi, if you are not rooted?
I hesitate to root, because I am still hoping for SkyGo.
Guys, I REALLY need some help here and I'm desperate. I'll give you some background info here. About 3 months ago I bought a used Transformer Prime, at the time I bought it I didn't realize it had CM9 on it, I didn't check out the tablet out enough. Now I'm not into rooting or flashing ROM's AT ALL...I couldn't care less about this stuff, just give me a product that works in stock form and I'll be happy. Now here's the problem, the speaker sounds like complete ass. I don't know if it's a hardware issue or if it's just an issue with CM9. Has anyone experienced an issue like that with flashing a ROM? I gave the tablet to a friend because "he knows everything" and jerked me around for 3 months with it, didn't even touch it so I'm on my own. I just don't want to go through the hassle of replacing a speaker that might now be damaged when it's a software problem.
I guess I need to know if it's possible that it's a software issue. The speaker volume is extremely low and very muddled. I have a feeling it's the speaker but I don't know. I don't know about enough of this stuff and no one wants to touch a tablet, for some reason if it was a phone the shops around here would be happy to help.
I might just sell this thing and take a huge loss and never cheap out on buying a used product.
Thanks guys.
Hi all,
Just looking to see if anyone has any answers to the issues im having with my android phone at the moment. I upgraded 2 months back to the LG G4 H815, i had all my email addresses set up including hotmail and one outlook address. The phone was running fine and ive found the battery was brilliant and lasts all day no problem with medium to heavy use. I even have music on my micro sd that i listen to as im going to sleep and can wake up in the morning and the music is still playing and has only used 15% of the battery which i found unbelievable. Anyway, the last 3 days the battery has been running dead after just two or so hours, and on going into the battery usage i noticed that Microsoft Exchange had been hammering my battery, and i havent changed any settings whatsoever so why suddenly is Microsoft exchange using 68% of my battery? I know all hotmail addresses have been taken over by outlook, but is it a hardware fault or a fault on the Microsoft side. My HTC One still deals with it just fine, wish id of stuck with my trusty HTC one m7 (brilliant phones) but like a fool i gave it to my wife!
Any help on this would be very much appreciated.
Regards, Martin.
Hi,
I have the same problem, did you found the solution?
Thank you.
Yes I did, don't add your hotmail or outlook addresses through Microsoft Exchange, add them in "other".
Seemed to fix the problem for me.
Good luck, hope it works for you too.
Hi there, i have no idea what is going on with the cellphone, since i used it for the first time i tried to charge the battery without any success, i reboot it while the usb-c was connected and it did charged, so now every time i want to charge it i have to connect it and reboot it. Also if i disconnect it after rebooting and connect it again it wont charge until i reboot it again, seems like it doesn't recognized the usb unless i reboot it. Could someone help me? Thanks

Install a custom Rom or MIUI10 latest beta build. If problem persists then problem is hardware related.
Been facing the same issue, @drchau did you find a fix for it ?
It is a hardware problem.. seems like it is somewhat common. I had the same issue last week. Tried several stock and custom os. Then realised it should be a hardware issue. Mine had same behaviour ( reboot to charge ) and then problem with otg not detecting. And usb c cable is recognised in only one way.
So booked a slot for service . Went to service today. Found three customers with same issues , and then the service center replaced my usb sub board and others too. Took one hour total. And everything is fine now.
Total cost is INR 700 for board + INR 350 for service + 19% GST. = 1250 INR.
They won't replace the port. It's a whole sub board . They replace it. You will get it for free if under warranty.
I have this problem with my Mi Max 3. I have to reboot OR for some reason it will charge via an OTG dock without rebooting (odd ... If I plug the same usb c cable in directly it doesn't recognize it.
A couple of times when I unrooted and reverted to stock unrooted, the charging issue went away.
I realize that many here are convinced this is a hardware issue but I also routinely disable/delete a lot of crapware and system apps via ADB .... Can't help thinking there might be a coded dependency issue.
I am in the USA so getting it serviced isn't an option ... I have 3 Xiaomi phones and would love to add a Poco F3 when I can afford to, but these charging issues are being reported with great frequency and I am hopeless at soldering.
If anyone knows of a repair shop in the USA they trust with their Xiaomi products I'd be grateful to know the name.
Thanks!

There's probably a couple mosfets and what not on that PCB. Maybe bad design or a manufacturing defect caused a solder crack or trace failure. Maybe a component.
These boards are usually inexpensive.
A relatively easy fix if so.

It could be (most likely is) a dependency especially if it happened right after the edits.
I prefer to package block rather than edit them out. Mistakes are easily corrected... most times.
Don't attempt soldering anything in these devices unless you know how to, not the place to learn.
Many though aren't soldered in, they're connected with ribbon cables more commonly. See a device tear down to find out.
A good phone repair shop should be able to handle it.

Thanks for your reply.
I'm pretty sure from video teardowns that the parts involved in the MM3 require soldering (there's some kind of board involved with replacing the port)
I still love the Mi Max 3 but it isn't worth a spendy repair because the carriers here are shutting down 3G and HSPA+ soon which only leaves me with FDD LTE 4 (not great where I live).
Repair shops aren't as expert in the states sadly ... most people here buy their devices from carriers.
I needed a camera replaced on my old Max but they didn't want to order parts so I ordered it and did the replacement myself (but only because I didn't have to solder).
If Asurion insurance from Amazon covers global phones I'll get my next Xiaomi insured. Too bad Xiaomi won't just let us ship at our own expense to their service centers in China or Europe.

Many times you replace the whole port PCB. If it's soldered on it could be a pain even with the right tools/experience.
You could try a factory reset to undo the disabled apks to see if that was it.
Thanks, I've tried factory reset and it helps for a little while. For now its still usable ... Rebooting to charge isn't a big deal. I do find it odd though that I can still charge via OTG dock without rebooting.
The bigger issue is what to buy to replace it. I don't trust Miui not to be buggy anymore and I have grown to hate constantly having to disable optimizations that inhibit sms, email and even calls (if I try to use TMO towers... AT&T MVNOs seem unaffected ).
I wouldn't mind doing all those steps once but my permissions don't stick for very long.
The TCL 20 might be worth a look...or maybe Realme if I see one with a bigger screen... I'm wedded to large screen models, mid price at best, with NA LTE band support ...
TCL also has a couple of LTE tablets with decent specs coming out ... but LTE tablets for USA export almost always ship with the dialers disabled so you can't make calls.
I'm trying to out till the end of June. By that time, hopefully the Poco F3 bugs will be resolved. Retailers aren't even shipping it here yet.

After the factory reset you need to find the akp that triggers this. Reviewing the most recent running and/or cache processes can narrow down the list.
Use Package Blocker PD MDM to clear the data in suspect apks. Unlike clearing the data in settings PD MDM leaves no nulls behind. Those silly nulls can mean big trouble.
Since it keeps returning the offending apk may be amenable to being package blocked depending on its function/dependencies.
This is how you find it.
Android Setup is a prime suspect. I cured a similar C-port error message like this by deleting the null marks in its data which showed as zero.
Happy hunting
