Non-original chargers suddenly very slow. - General Questions and Answers

Phone: Lenovo P2
All problems occurred while charging overnight, say 7-8 hours of charging time.
Normal charger completely charges the phone, no problem it seems. Output 5.2V/2A to 12V/2A, it's a fast charger.
Non lenovo charger, an Oppo Vooc charger, rated at 5V/4.5A
Other chargers I tried are rated at like 5V/1.5A
Both charge my phone 20-30% overnight.
All other chargers used to work fine and fast.
Anyone know what could be the cause of this? It's bugging me, and i've got about one month left on my warranty.. (but the repair centre lenovo uses in my country is also the worst ever)

Thank you for the tip, but in this case I don't need another charger or anything. It's just that all the other chargers became slowly at some point. That's the problem. (and the solution wouldn't be to get another charger, I still have the original one, I just want to be able to charge normally on all chargers)

That sounds like some kind of software running in the background causing excessive battery drain.
Here are a few possible causes:
1) installing stock updates without wiping the cache partition after the update. Failing to wipe can make a lot of things buggy.
2) installing too many social media apps, these run constantly checking for updates and notifications, causing excessive battery drain(to the point that the battery barely charges slowly).
3) a failing battery can cause a slow charge.

Battery/Charging Queries

Hello Friends, I have a few general queries.
What is the best method or practice to charge a cellphone battery? Should a user allow the device to completely run out of charge/power such that the device shuts down or switches off? Or should the user make it a point to charge the device once the battery level is between or depleting from 20% - 10%?
Also, does intermittent charging reduce the life span of the battery? The reason I ask this is because a cousin of mine has a habit of charging his cellphone (Sony Ericsson Xperia Mini Pro) every now and then. It does not seem to matter to him if the battery level is at 80% or 50%.
Personally, I have a Samsung Galaxy Note.
Thanking you in advance and awaiting your apt responses.
EDIT
I apologise if this thread is in the wrong section. Perhaps it belongs to the Questions and Answers sub-category of General Discussion. I urge my Superiors here to move it to the appropriate category/forum they deem fit.

My best experience when first getting a new phone is to do a full charge, then let the battery drain completely, and do another full charge with no intermittent taking the phone off of the charger, after a few times of doing this it should break the battery in.
Though some say this does nothing and is merely a myth - I like to think it's true as I have seen results.
I always do the charge, then full discharge, then full charge once on a new phone. From then on I don't pay attention.
I charge every night over night on my night stand. Then use phone throughout the day. If it is a particularly busy day I charge as needed whether that is the regular charger or cigarette lighter charger in the car.
Thank you icepally and 85gallon for your replies.
After I received my device, the very first time, I inserted the battery, powered it on and continued using it until the battery level was low (somewhere between 15% - 10%, although I cannot remember precisely ).
Should I have plugged the phone for charging immediately after inserting the battery or after powering it on?
Also, I did not follow a practice/order of complete 100% charge and complete 100% discharge.
Do any of you reckon what I have mentioned in the above 3 paragraphs will impact the battery life span of my device?
I apologise for my naive and paranoid queries. I am a noob!
Thank you once again for being patient with me.
You should charge any li-ion battery fully and then discharge completely without interruption as often as possible. Most ppl who complain the most fail to get this. This will give you longer charges by up to 25%

Hello Friends, I have installed BatterBatteryStats 1.0.0.0 on my Samsung Galaxy Note.
How do I use this application to serve me better? Also, is the said version dated or it is enough to be used on my device?
After installing the application, I am clueless about its functionality.
Thank you all once again for being patient with my stupidity.
Wipe Battery Stats, is it necessary?
Hello all, I would like to know if it is recommended that a Wipe Battery Stats be performed every time one flashes a different custom firmware and or a custom kernel?
There are suggestive opinions stating that such a practice allows the kernel to 'settle in' (for a lack of a better adjective), thus making a difference in battery life and performance.
Also, an acquaintance from my neighbourhood pointed me to the following article, http://lifehacker.com/5786717/get-b...ted-android-phone-by-wiping-its-battery-stats, which aroused the above query. My device is a Samsung Galaxy Note GT-N7000.
I have not followed any such acclaimed practice till date, and since I am naive and daft, I felt my query will be best answered by the experts on this wonderful community. Thank you all for your patience.

another easy question to ask.........first to do after buy a phone is to drain da battery first, do a hard drain and then charger a bit juz to make sure ur fone can be booted, boot ur fone n do a factory reset, drain it again, simply rebooting n shutting it down to drain it, after that, charger ur fone merely for 1 minute in off mode n boot again ur fone while charger still developing n make sure u close da sleep mode while charging until it fully charged. There u got ur fone fully regenerate da stat without using any software. then u can charger anytime,anywhere n anyplace as android hav excellent battery management.

post-mortem, thank you very much for the link to a technical reference. Upon reading it, I have learnt and thus become aware of three important aspects -
1] Never overcharge the battery.
2] Never discharge the battery completely or too low.
3] Power off the device and charge.
:good:
But is it absolutely compulsory to follow point number 3, and charge the device after powering it down?

I would say this is only a real issue if the device has high drain while charging. Like if you charge while on a call, or while using navigation. If you only do such things occasionally, I'd bet that the device will reach terminal utility in some other way, before the battery does.
-- Sent from my TouchPad using Communities
For me, a new phone must be fully drained when used for the 1st time, and charge it for 5 hours.. It's always the common sayings for a lithium ion batteries.. and then after that you can charge the phone whether it's 20% 30%, etc.. then once a week fully drained the battery and charge..
Also. Overcharging will destroy battery integrity. Not like just charging overnight but if you just constantly always try to charge it and leave it charging when full for long periods of time. Its scientific.

Hello everyone.
When charging a device, either via AC mains using a travel adapter, or USB, is it a compulsory practice to use the stock original cable which doubles up as the data cable, to do so?
Just as there are after market premium batteries from the likes of Anker and Mugen, are there after market premium cables available as well? If there are, would a single after market premium cable be compatible across multiple, if not all devices?
The stock original cable of my Samsung Galaxy Note GT-N7000 has started malfunctioning. I contacted Samsung India's customer service to enquire about the availability of the said accessory, and upon the customer service agent's suggestion, I got in touch with the local Samsung authorised service centre, where an agent informed me, the cable will have to be ordered and it would take between 15 days to a month, to arrive at the local service centre.

1. yes
2. not that im aware of, but that doesn't mean there is not. most of them are junk though.
3. you could try ebay. sometimes people sell extra parts cheap, but i dont know how you would tell if it is authentic other than contacting the seller. many of the supposed oem stuff is just aftermarket china junk.

It really doesn't matter, as long as it's from a good brand. You're not going to damage anything if you use an LG cable on a Samsung phone. You're not going to damage anything if you use some crappy no-name cable, but you should stick with reputable names just for the assurance of longevity and steady connection (especially if you need it to connect to a computer). If you want to find an OEM Samsung cable, just find the cheapest/quickest to ship, and it'll work just fine.
The actual charger though, can be a different matter. ALWAYS go with a reputable charger, preferably the one that came with the device. But even the latter isn't all that important. Mainly you should worry about the charger malfunctioning and cooking your phone. But if you go with something name brand, it's extremely unlikely that you'll damage your battery.

The long shipping time is because you're requesting a specific part with a specific number. Just find yourself the quickest/cheapest Samsung, LG, Sony, Motorola, HTC, or other name brand cable, and you'll be just fine with it.
contrary to what planterz posted, on some phones, newer ones more predominantly, some will not charge properly or as quickly as possible if you don't use the proper factory cable. case and point is the lg g2 i have. fast charging doesn't work with crappy aftermarket or non lg cables.
@Planterz and @bweN diorD, thank you very much for your replies.
I have been charging my device alternately, sometimes using the stock cable of a BlackBerry Bold 9700, but mostly the stock cable of a Sony Xperia E (C1504).
:silly:
The Samsung OEM cable is available for purchase online at Mobile Fun India, http://in.mobilefun.com/46026-samsung-micro-usb-sync-charge-cable-black.htm. But, the shipping charge amounts to slightly above half the price of the OEM cable.
I have also looked at the Belkin MIXIT Micro-USB to USB ChargeSync Cable (F2CU012bt04), http://www.belkin.com/us/F2CU012-Belkin/p/P-F2CU012/, which I am very inclined to purchase.

Hello everyone.
How can the integrity of a Lithium Ion cellphone battery be tested? What is the apt 'hardware' method to do so? Also, would using an app (software interface) yield a convincingly accurate result?
The stock OEM battery of my device (Samsung Galaxy Note GT-N7000) has begun draining rapidly, and thus, I am keen on assessing its capacity related aspects and diagnosing its charge storing/retaining ability.

I await your valuable guidance.

Battery issues ? Consider a new charger

Just wanted to report my experience with battery life which seemed to be degrading over time and not really reaching 100% every time anymore. I did the usual tricks to get the battery to charge fully like pulling the battery when the phone is still plugged in, but had to do it every couple of days because the battery would max out at about 80%. Bought a new charger off newegg (Samsung oem), problem solved. Charges faster than ever, and holds a charge better too. The old charger is the one that came with the phone.
On a related note, I first bought the new charger from Amazon, but returned it because it turned out to be a fake. Read the Amazon reviews, I'm surprised they still sell it after so many complaints. Newegg is the way to go for this one.

Its been established many times that our phone doesn't like many chargers other than our cube. Whether it was a difference in power output or something else I can't recall as for your issue it sounds like a wake lock of some sort may have been created with said charger that would cause a faster than normal discharge rate causing the charger to be unable to charge past 80% the effect could also be that the output of the charger was not 1amp and the phone couldn't get what it needed in the time you allotted. Really I can't say exactly what the issue is in your case but if you had searched you would see much of this has in fact been documented.

If you actually read my post, you'll know that the new charger is the cube, that is what I meant by OEM. I posted this so other users can consider buying a new charger if they've tried everything else and failed. No need to do the "search and you would have found out" response for this post, cause no question was asked, I was merely sharing my experience.

Phone won't turn on after overnight charge.

I found that my phone wouldn't turn on at all after charging it overnight, which I do every day. Might I have to get a battery replacement? If yes, two questions: where and how much? Or what are some things I can try out. I have also recently flashed a CM 10.1 ROM and have gotten battery problems with it like overheating and drainage.
*update*
Most likely not a battery problem since my computer was able to detect it. I also plugged in my MHL cable and nothing happened
You're not the first person with this issue. It's in a bricked state. I'd leave it unplugged for a while and then try plugging it in overnight again and see if you can power it up.

I saw a similar post but the person's phone had a red light and also tried a search but couldn't find another thread with the same problem. And thanks for the suggestion man! Is there an alternative way so I can deplete the battery? I can't tell if the phone is on or off since my computer doesn't recognize it anymore. Would it be safe to cover it with a towel so the heat can do its work on the battery?

The red light might not come on at first, but might after charging for a few hours. Just let it charge (wall charger, not from a computer USB) and leave it be for a while.

Charging efficiency for Li ion batteries is 97-99% regardless of temperature, as long as its above freezing (which I assume is not your situation). While higher temperatures may reduce internal resistance slightly (and therefore a minor improvement in charging time), I'd say its not worth the risk of covering the device, as thermal runaway can cause overheating, and even a fire or explosion. Anything near room temperature is fine for charging, and heat is generally the enemy of electronic devices.

All HTC devices come with a 1-year warranty standard. AT&T doesn't offer extended warranties, only insurance (which I never get either).
If you tried charging the phone overnight, and short of various button combos (I've seen one guy on here, that for some odd reason, the phone only turned on when he did the hboot combo while the phone was plugged to the charger) there is not much you could have done, and it was likely a hardware issue. Which is a justified warranty replacement.
AT&T doesn't care if the bootloader is unlocked, rooted, custom ROM, etc.

[Completed] [Q]

Hi Guys,
I hope someone has a clue whats going on with my fone.
(after few months) The charger that came with the box had issues charging , usually I had to bend and twist the cable to charge. So it went like this for a few days and then one day It was very low on battery so I connected it to the charger but it wasn't responding
Finally it died I tried the twist and turns but the cable didn't work , few days passed as I couldn't find a similar charger(as most of my family uses Iphone including me)
Now a friend of mine took the battery out and charged with an adjustable charger, I checked the battery has charge now BUT the mobile isn't switching on.
Can any one help ?
All comments and Ideas appreciated
Thanks in advance

Hi
Thanks for writing to us at XDA Assist. Which device are you talking about? Does it have a removable battery or did your friend need to disassemble the device to remove the battery?

How exactly did your friend charge the battery? Did he hotwire the charger directly to the battery? If so, he's probably damaged it so you'll need to purchase a new battery.
Transmitted via Bacon
He used a portable charger, its kinda hot wiring I believe.
Is there a way to be sure the battery is gone ? Coz you can still feel the charge in it.

Mediapad x2 freezing when charging and original charger

Hi!
My x2 started to freeze when charging. I started to wonder if it's because of the charger, because I lost the original one and just started to use a samsung charger I had in the drawer. Although I've been using it for a year now..
If someone would be so kind and post a pic or the details of the original charger so I could try if that would remedy the problem.
Thx
My experience is that the original charger is actually not as good as the Samsung charger by any means. The original charger I believe is actually out putting less than in this specification which is 2 amps. The Samsung charger is much better and charges the phone faster. However I have also noticed something really weird in that sometimes after charging the phone overnight my battery is only at around 80% or so and this is random because it only happens sometimes and most times it charges fully. Not sure if anybody else has seen this Behavior
Please use the QUOTE feature when replying to me to get my attention. Thanks!
So the original charger is 5V, 2A? Thanks. I'll try some other charger. It may be busted. Or I have to do a factory reset and see if that fixes the problem

Yes, yesterday my 2 year X2 started to do the same. I was stunned when after short time of charging I realised so phone was freezed and got quite hot on the back. Orange light slowly blinking and after restart it was 80% charged. I suppose it's problem with original charger. I have to look for another one...
//Edit - this is not original charger but Samsung - 5V/2A which till now was working without problems. It's not depends on charger type, occurs even during connecting to USB in PC.
//Edit - if you switch off charger and let it be some time, the phone starts anew. But, what is interesting, newly made TWRP nandroid backup turns out to be delted from SD card.during this 'blackout'..
//Edit - it starts occur not only during charging.. But in such case after self-acting restart phone goes to bootloop so it is needed to restart it manually and then it starts realatively quicker than normal.
Hmm.. could it be the battery dying? I'm using simply international B202 ROM. If changing the charger doesn't help I'll flash the newest ROM in and if even that doesn't fix it I guess I'll change the battery.
Same problem on mine but not when charging. Try my LineageOS 13 ROM, it's faster than EMUI and should make the phone feel faster again. I think Huawei is pulling an Apple and slowing our phones down as the battery dies.
I did a TWRP factory reset and the problem vanished! Hope it won't come back.. I'll try your lineage ajsmsg78 if necessary thx for the tip and all your work!
I have been having very unusual battery issues lately and I do not think it has to do with the charger at all but rather the physical battery itself.
Symptom 1: After charging overnight, by battery is only approx 79% charged
Symptom 2: Battery does MUCH quicker
Symptom 3: When battery gets to approx 20% it does right away giving the popup message that the battery is dead and the phone will turn off in 30 seconds - sounds like defective cell
Symptom 4: Putting the phone on charger when battery is critically low (10%) for 3 minutes, the battery level jumps to 90%
Does anyone know where we can buy a GOOD QUALITY battery to replace for the X2? I know there are some links on AliExpress but I do not know if I can trust those aftermarket batteries in terms of quality and life and reliability.
Also does anyone know how easy it is to replace? I have good soldering skills but don't know if here is more involved than that.
Edit: In the unlikely event that this is a software issue, I might try to clear my "batterystats.bin" file.

Unfortunately all those symptoms talk about battery dying state...

I thought about it either so will try it soon. Maybe switch to Lineage OS but I greatly appreciate smart case function in EMUI...

I took apart a Mate 9 and replaced some insides and it was really easy. The X2 shouldn't be any different. You don't have to solder anything, just pull up the flex cable connecting the battery to the motherboard and then pull on the tab on the bottom of the battery to remove the sticky tape underneath it then use some force to pull it up. I only see aftermarket batteries for the X2 so you may not have any other choice but to buy one of those. Your battery is definitely dying though.
