[Q] Need help with a charging issue? - Hardware Hacking General

Hi,Everyone!
I have a Qmobile A700 (1GB RAM, Quad-core) running a 4.1 jelly bean stock OS. It is not rooted BTW. The problem I'm facing is that since last couple of days it's charging has been significantly slowed down. Usually charges completely in 1.5hrs but now it takes 12 hours to increase charge by 40%. Also when in use it crashes, just like if you taken the battery out and when tried to turn back on it says only 1% battery remaining, although before crashing it is more than 40%. How can all that charge disappear within a couple of seconds. The only major change I did with the mobile was that a week earlier I replaced its 8GB SD card with a 32GB SD card. It supports SD card upto 32GB. Does that have any relation to this problem? Please help ASAP!! I have tried using all kind of chargers, the charging rate is still slow.

That sounds to me to be a battery at the end of its life. Having charge % drop that quickly indicates that while the battery still "charges" the amount of energy it stores is far less. My recommendation would be to try and find a new battery from a parts dealer or something like that and swap it yourself. Usually battery swaps are very easy as long as you can figure out how to open up your phone to see the circuit area.

My battery issue solved. It IS card dependent (atleast for me).

I had been using all sorts of ROMs (both windows and androids) to test the best battery life. All this was on a 16GB class 2 (the stock card for tmous). None of the ROMs gave me more that 8 hours of "less than moderate" use.
I then heard that the card made a big difference. Anyway, I also had 3 other cards laying around in the house, all 2 GB ones (all class 2). I had been running mattc 1.6 for about a week since I preffered his ROM. I copied the android folder and other related folders from my 16GB to a 2GB Class 2 Nokia card (came with a tmous nokia phone).
Now with rom on the nokia 2GB card, I went to office with about 50% charge with a charger in hand to charge in about 4 hours or so. Checked after 4 hours and still had about 40% left. Felt good. Finally, found a solution to the battery issue.
Now I installed the "Current Widget" to see what the differences are. In the meantime, I also went and bought a 4GB class 10 (Transcend).
My settings are:
Fetch email every hour.
SetCPU Battery < 100: 899 MHz
SetCPU Screen Off: 245 MHz
Current Widget: log in file every 1 minute.
Here are my results for Mattc 1.6 on various cards (over a period of 5 days):
16GB Class 2:
avg 58 mA current during screen off.
avg 400+ mA when on.
battery drain at 6% to 7% per hour standby.
2GB Class 2 (nokia):
avg 6 mA current during screen off.
avg 350 mA when on.
battery drain at 1% per hour standby.
4GB Class 10 (transcend):
avg 56 mA current during screen off.
avg 400+ mA when on.
battery drain at 6% to 7% per hour standby.
2GB Class 2 (sandisk):
avg 58 mA current during screen off.
avg 400+ mA when on.
battery drain at 6% to 7% per hour standby.
So my findings so far are that the battery drain IS because of the card you use. It is highly dependent on the amount of current being used during standby. I'm lucky I found the nokia 2GB card and tested it or else I would have used the 4GB Class 10 and come back and said the battery drain is not due to the card. I've seen other threads saying that class 2 will cause heavy drain, which is not the case with my setup.
Whenever I start Android, I kill all processes once. Sometimes, I have to restart Android on the 2GB nokia if I see 60mA current for 5 mins or more of standby.
That's verry interesting !
gues i'll buy a smaller card then.

The card might effect it some, but the large chagnes you report are due to problems with the build itself.

Hmm not convinced I'm afraid, because I have Sandisk 16GB Class 2 card running FroyoStone V2 with ChuckyDroid Rom and I see 5-7mA in standby all the time.

And are you getting good battery life with the 5-7mA in standby mode?
It cannot be ROM dependent cause I used the same Android build on different cards with different results.
I really want to use the 16GB card so I can store a lot more data but as of now, my nokia 2GB is the one for me. I'll keep testing other cards that I can get hold of.

Well, the smaller card didn't solve it for me. I tried with two other 2GB cards but the nokia one was the one that worked. The other 2GB cards resulted in the same 55 to 60 mA current on standby resulting in high discharge.
So you'll have to try several cards... As the member above is getting low current on the 16GB.
Its almost like the "wand chooses the wizard", where you'll have to try several cards to find the right one for your phone.

Well yeah exactly what I would expect in line with about 6mA current draw. It just eats battery whenever I do anything with the phone though that's the issue for me. Pretty much the same, maybe slightly better than when I ran Winmo.

4-day battery life !

I've been frustrated with the inconsistency of the battery life on HD2 WP7, when with the same settings you get dramatically different results on different days.
However, I am pleased to announce that I was able to get 4 (FOUR!) full days of battery life on 1 charge from my phone this week. Admittedly, it was on light use, however, during this time the phone was never powered off or connected to a computer. It was mostly on standby (not airplane) mode, with auto backlight on, location on, but wi-fi, data and bluetooth off most of the time.
During these 4 days I did the following things on the phone:
- talked for 1 hour total, using bluetooth st. headset;
- browsed web for 1/2 hour on wi-fi and 3G;
- watched 8-minute YouTube clip;
- with camera: recorded three 2-minute video clips on 720p and took 7 still 5MP pictures with flash off, using SHCameraApp;
- browsed Marketplace for 10 munites, installing 1 app;
- checked emails twice a day;
- played audiobook for total of 40 minutes on speaker and BT st. headset.
Normally I use it more heavily (was getting 2 full days with moderate usage on WM 6.5), but this experiment is encouraging.
I am using Moon Light ROM with 2.15 radio on U.S. T-Mobile, with stock 16 GB class 2 microSD card. I haven't installed any battery-related tweaks. I need to clarify again, that with this ROM and same settings I don't always get same results, and the battery indicator sometimes doesn't show full charge even with green light.
At the start of the experiment, however, the phone was fully charged through USB connection to PC.
wow...4 days is amazing.
ive been saying this for weeks, IF you can get the battery to fully charge its actually fine. almost everyone complaining that it doesnt last very long hasnt fully charged the battery, and i dont blame them for thinking this because everything on the phone is tell you it is charged.
i just used an external charger, got another battery and swap them everytime i run out of juice!
if 4 days is achievable then its ok for everyday use.
i found many people complaining even on native wp 7 phones like htc trophy lasting only a few hours...
so I think its really not HD 2's fault

I agree...my friend has an HTC 7 Trophy and the battery acts roughly the same as on my HD2.
same here, battery life is no different for me on 7 than it was for 6.5, something else to note is that for me it will say it's low for 3 or 4 hours at least before finally running out

Does your HD2 do any random reboots using the 16gb class 2 card, because mines was doing that using xbmod

no point asking questions like that because it doesnt matter what anyone else has, i could buy the exact same card as you have it may work perfectly
no two cards no matter how identical they are, are the same, luck of the draw.

Yes, I had the random reboots problem at first!
But I completely resolved the problem by flashing the 2.15.50.14 radio.
I wrote a detailed post on that, search for it:

Bull. And I have a HD2 and Trophy and the Trophy gets at least about 1.5times longer battery..

Unfortunately not all phones act the same do they...even between HD2 you get those with long battery and those with short life span. My friend Trophy does run the same as my HD2. You will notice some users get up to 2 days on their HD2...some struggle to get 12 hours...thus battery lifespan varies...i'm getting roughly 8 hours with heavy usage and over 24 hours with light usage on my HD2. Keep in mind that it does vary between users and consider that before posting bull to someone as the battery lifespan does vary a lot at the moment.
Edit:
BTW...what does your Trophy get compared to what my HD2 are giving me. Also I read some peoples HD2 overheats especially while playing games...mine aren't even with playing games a lot on it...maybe I am lucky but I do think somewhere something like SD cards, radio etc does play a role in all of the above.

how about switching to android to do the charging and then switch back to wp7 once fully charged? that way we can find some use for our android ;-)
I have two batteries and one is in separate dock that has battery charging at rear and the other battery is in the phone. I charge the phone all night with normal charger plugged into phone and in the morning at about 7am I unplug from charger and go to work, by 2pm to 3pm the phone is flat. I have email sync, bluetooth, WiFi and location on. I then get home at 5 to 6pm and grab battery out of separate charger that has been charging all day and phone will be nearly flat by 11:30pm 12AM.
I also own a HTC Mozart 7 and with all services running the same as the HD2 and the battery time on the Mozart would be double and it has more use with calls.
Can someone explain the "make sure your battery is fully charged" comment that is in this thread?
Update
Here is an update on my original post #1.
There has been exactly 48 hours since I charged my phone (through USB) at the end of the 4-day experiment. This time, after 2 full days, the battery indicator shows about 2/3 (!) of the charge still left.
To be precise, I didn't do much with it during these 2 days, only listened to audiobook on speaker for 20 minutes, manually checked email few times, downloaded attachments, and did some light web browsing for 10 minutes.
Still, I haven't powered it off, and it's been on automatic backlight, so only 1/3 of battery used in 48 hours is a very encouraging sign.
The phone (and battery) is just under a year old, and I have a habit of not charging the phone until the charge is low, so maybe that's a factor, but after switching to WP7 I was having battery problems like many people describe here.
My battery atm is sitting on 66% and it was last charged just over 12 hours ago. I havent spoken much on it today except for 1 call...sent 7 messages and played 4 turns on Spell It since then...thus light usage.
Strange thing is like some mentioned in threads...at the start the battery ran down quick...about 45% during the 1st evening in 8 hours...when not used. Now its lasting ALOT longer...its as if it settles over time.
in my experience it has to do with your data being off.
XBmod-WP7-V1.04b
radio 2.12
4:30--11:30---7h Data-off 3G-off Bat-75%
00:00--9:00---9h Data-off 3G-on Bat-94%
what i mean by make sure your battery is charge is that windows may not charge your battery fully, but it may report your battery as being full, some simple maths should do, if you have a 1Ah charger your battery should only be full around 1.5 hours later depending on usage whilst charging. now most USb ports only pump out 500mAh so again taking in to acount that your phone will be using some of that power to run its self and your looking at around 3 hours charge time
Now sometimes i find that if i charge my phone and then stick the battery in another HD2 running WM6.5 its only about 60-80% charged, i find that inorder to get a full charge without faffing about i need to use an external charger or use another HD2/ROM. if thats not an option then i find restarting and charging, or unplug and charge usually does the trick

Phone shut off at 32% and only charged 7% in 1h30m with fast charge

I work 8 hour shifts and my 6P on Pure Nexus lasts through the shift with ~30% when I get home.
I was listening to music through Bluetooth and when I turned off my headset around 5 hours into my shift, my phone shut off and wouldn't turn on. I was in and out of the freezer, so I thought it was the cold. I got home, turned it on and plugged it in and saw it had 32% left.
An 1h30m of charging and it only charged 7% which is really unusual and is the first time.
I have AccuBattery Pro and it is saying it's going to take 10 more hours to fully charge using fast charge. Android lockscreen says "Charging rapidly. 12 hours until full."
Also in AccuBattery, although my design capacity for the battery is 3450 mah, it normally says estimated capacity is 2200, but is now saying I have over 5000 mah in capacity.
When unplugged, it has a screen on discharge rate of 50-70%/h when the average is 23%/h.
Is the battery dying? I thought it would gradually decrease in capacity and not suddenly change overnight.
When my battery bug hit..it just hit. No warning signs or anything. I was crapping out anywhere from 60%-10% and everywhere in between. I bit the bullet and RMAed for a new battery (they gave me a new screen too for whatever reason) Before i sent it in my Accubattery stats were saying i was at 75% capacity and now ive been at 100% capacity since i got it back and i can happily go from 100%-0% like its supposed to.
Although your situation does sound unique its almost certain you'll need a battery replacement.. or try a new ROM and see if it keeps happening.

Unfortunately, I got my phone from Rogers around November 2015. I don't even know what they can do about it. It's been averaging about 14%/h charging which is about 1/3 the speed. I've been using the same ROM for several weeks with no issues and haven't installed anything new lately other than app updates. I can try upgrading Pure Nexus, but it seems like they have a power menu bug at the moment.
Do you think your charger could be broken?

My wife has a 6P also. I was trying her charger and it's the same thing. I've rebooted twice. It's still draining at least about twice the normal average when disconnected.
So it's roughly draining at about twice the normal speed without doing anything and charging at a third the normal speed.
I seriously can't afford to replace it. I regret choosing a phone without replaceable batteries and will not do that again, which means no Pixel phones. At least I still have my Galaxy Note 3 which still works.
if i were you id backup the entire phone (or whatever is importannt to you) to my computer and download the J factory image and do a fresh clean flash and pray that it clears out whatever is going on. Sucks to start fresh, but worth a shot

I use FolderSync to backup my phone nightly to my NAS server.
The slow charging speed may be due to high cpu temperature. It was hovering around 40° for whatever reason. I set it down on a cold granite window sill and the temperature dropped to 35° and was charging at twice the speed, but still slower (1000mah vs 1550mah from before). I've been holding it for a while and the temperature is again going back up with charge speed slowing. Again, I've never had this happen before.
Thanks again, I'll probably restore the phone and bring it to Rogers later this week to see what they say.

What are the possibilities of a phone's perfomance related to battery?

I bought my note 3 back in 2014 January 2, until then never changed the battery for once. I did bought a new phone and it's lying around in my house. THe phone's battery was weakened to this point where just booting up the phone takes ~15% charge. And if I browse Facebook with Mobile Data(4G) then 10% drains in under 5 minutes.
Also, if I play games like "Clash Royale" my phone turns off automatically(also phone heating up quickly) despite my charge is around 70-80ish
Are all these reasons due to my weak battery? I flash my phone new rom every 3 weeks.
Galaxy Note 3 SM-n900(exynos)
Update: I'm using a custom rom, is this why it is showing A9000? And if I recall it correctly, Note 3 battery comes with 3200mah battery why is it showing 2550mah?
After 3 years your battery loose about 50% of it's original capacity so I recommend replacing it anyway.
Every time you flash a new rom (why are you doing that?) the cache is rebuild which takes some time and drain your batter a bit (in your case many bits).

get a new battery and flash roms with 100%, you will be good
Thanks for the response fellas. I ordered a battery from Ali-Express, gonna take a month to arrive here.

Rooted SM-G530H Suddenly extremely high battery usage

SM-G530H rooted with stock ROM. Phone was fine until a couple of days ago the started eating the battery, dead in 3-4 hours. Bought a new battery, charged it and the same result. 3-4 hours. no more. This is in standby. Shut the phone off, charged it to 100%, unplugged it and waited an hour. phone turned off. Still 100% battery. Booted and Installed CPU-X to try to determine if something was "hitting" the CPU or memory was full. CPU looks pretty normal, one core parked the others at 1-2% with an occasional excursion to say 30% for half a second and back to 1-2 %. During the excursion the parked CPU does not come online. One thing I notice is that CPUX says the phone has 884 MB RAM where specifications say 1GB. Wondering if something has happened to part of the RAM.... I am trying to determine whether to wipe and reload the stock firmware or I have a hardware problem.......any help or suggestions welcome.
Note that 2 different CPU programs say 884MB of RAM. Also note that the phone has very few programs on it other than whats on the stock ROM.
Did a search for high battery usage and didnt find anything like the problem i am having.
Thanks.
Please note I mistakenly posted this to the General forum and realized my mistake. My apologies to all.
