Very nice! Thanks!
[Droid Incredible General] hgrimberg:
Is it true that car chargers damage the battery?
[Droid Incredible General] POQbum:
entirely depends on the car charger. In general no, but some are known to overcharge. This goes really for any aftermarket battery charger.

If you're charging via USB than you're safe.
[Droid Incredible General] Zalatorisaurus:
Very nice research, sir.
[Droid Incredible General] rubber soul:
thanks for this. really great information here that i wasn't fully aware of.

regarding chargers, i always figured usb was usb was usb considering it is a standard and all. it does seem that some chargers behave differently than others however. one wall charger i have disables my touch screen and my car charger seems to make my phone really hot. i'm guessing this has to do with different current ratings of the chargers or something. any advice with regard to this? do i only buy htc branded chargers (and when i move to another phone i have to get new stuff?). that doesn't seem right.
[Droid Incredible General] byrong:
Pretty much, yes. Even when they claim similar ratings, different chargers put out different currents. Cheaper units will generally have lower quality control and have the potential to introduce more problems (like your experience of the touch screen becoming unresponsive).

I wish I had hard and fast advice, but I don't really. There's definitely a balance to be struck between the $40 brand-name chargers and the $2 generic ones. I am not well-researched enough on the subject, however, to offer a specific brand or model recommendation.

Once you find a good one though, you should be able to just stick with it; MicroUSB has become the industry standard.
[Droid Incredible General] hgrimberg:
The lady at the Motorola store said to me that car chargers are only for emergencies and that they dont have to be used like a wall charger. She said that she learned this at a Motorola seminar.

If you think about it, a car charger gets continous current instead of alternative current, so there must be a difference.
[Droid Incredible General] byrong:
I don't understand why you'd ask the question if you believe that you already had the authoritative answer.

My opinion mirrors POQbum's advice: it depends entirely on the charger.

In any regard, this is a hotly debated topic on the net. A few seconds of Googling will turn up more arguing than you could read through in a lifetime. No use in dragging that debate into this thread.

That's why wall chargers are referred to as AC Adapters.

A properly designed wall charger converts 120V* AC to 5V DC

A properly designed car charger converts 12V DC to 5V DC

No matter what, your phone shouldn't just be hooking directly into a raw power line.

*Varies by country
[Droid Incredible General] hgrimberg:
Ok, so what is what you personally do? Do you often charge your phone in the car using a Motorola charger? Do you personally think it is safe and that there is no difference at all with a wall charger?

Thank you.
[Droid Incredible General] byrong:
I rarely have to spend long periods of time in the car, so I've never developed any strong opinion on the matter. I have a car charger that I use for trips that require navigation, but that's less than once a month.
[Droid Incredible General] k1mu:
I can't see how an automobile adapter which outputs 5 volts DC can be any way different from a wall charger that outputs 5 volts DC. The phone can't tell the difference and won't charge any differently.

Comments about the input (DC from the car, 12-14 volts or so) or the home (120 volts AC) aren't relevant since the charger should be putting out the same 5 volts DC.

If Motorola is saying that their car chargers are somehow different then they must be putting out more than the specified 5 volts DC. If so, then they're defective. They can't claim that EVERY car charger is equally defective.

(For reference, my undergraduate degree is in Electrical Engineering. If you're going to disagree, please explain why.)
[Droid Incredible General] hgrimberg:
Thank you very much for your technical explanation. It seems you know what you are talking about and I'll take your comment as the last word on this subject. I don't know how Motorola can be teaching their representatives that the car chargers are only to be used for short periods of time and in cases of emergencies and not as real chargers. Well, maybe this representative didn't understand it very well.

[Droid Incredible General] byrong:
Personally, I don't do it. It seems to be one of the more touchy topics when it comes to batteries, with arguments devolving to "I don't care what your fancy science says! I know what I've seen!"

Example from XDA: http://xdaforums.com/showthread.php?t=1169979

I would recommend reading around on Battery University, for example this article:

[Droid Incredible General] Toledo_JAB:
So the Chargers supply standard USB 5v dc to phone, and the drivers/kernel use it as programmed. So the phone actually charges itself? Right. So I am ok plugging it in overnight but not running below 20% or red.

I hope my X10 battery recovers from my ignorance. :-(

Excellent article. Very informative and insightful. Thanks.
[Droid Incredible General] akita16384:
A lot depends on how the car chargers are designed although the same can be said about AC-DC adapters.

Car chargers just need a voltage step-down and can be down in a few ways, either with a 1) transformer or 2) a cheapo resistor step down. Either way, if the charger has no proper voltage or current cap protection built-in, surges in current can affect or damage the phone. I reckon that is why starting the car would cause the car radio and other stuffs to do 'dim'.

Now, most decent chargers would have simple diode or fuse protection, so it is prob ok.

The same dangers can be true for ac-dc adapters. If proper protection is not built in, the phone can be fried if lightning were to strike the building. But this extends beyond just the adapters, but to both the house earthings, power mains circuit breakers and wall sockets.

One thing that may have it going for ac-dc adapters is the rectifiers used for converting ac input to dc output. They also act as voltage regulators and protection. They would mostly fry first in the event of a current surge before killing your phones.

But again, not all ac adapters are equal.

All said, make sure your charges have the FCC and EC (and whatever Cs there is) certification, or you could open them up to see what wizardry is inside, and solder in diode or fuse protection if there aren't any! :cowboy:
[Droid Incredible General] LiquidSolstice:
And three years later, regardless of what phone you own, this is an extremely well written post and is helping people make better decisions about bump charging, especially those who have phones with non-removable batteries.
[Droid Incredible General] makbil:
Thanks for this informative post. At least people can now make informed decisions on if they want to bump charge or not and also if it will help them occasionally to do so. There's a trade off in everything and rather than say bump charge is bad, people should just think of what they are gaining versus what they may be loosing and make a decision based on that.

[Droid Incredible General] kryptonic rocker:
Bad battery gauge

hi, i have an S4 mini GT I9192. i have been having issues with my battery. at first, my phone would go off at 50%! and it wouldn't come back on. after pluggin into a charger for 5 minutes, it would turn on at 0%.

i later started charging it upto 50 percent and then using it untill it drains, but whenever i let my phone goes into sleep, it goes off! especially near 30%

when also charging my phone, when it reaches 57% it automatically jumps to 100%

if i reboot, i loose close to 20-30%!

i thought it was a battery issue so i bought a new one and it still behaves the same.

Kindly help:(:(:(:(:(:(:(:(

I veen bump charging since my s3, but not sure if it works so much with the new phones. I have a note 5 and i bumped it a few times but the kernels are still fresh as the phone is barely 2 months old so cant really gauge yet. Definitely worked on my past phones tho
[Droid Incredible General] mobi74:
Good info, but when my phone lose 10% after unplug the wall charger, also lose a lot of charge on screen on, so I after about 2 monts of usage i make a backup of all app+data, make Full Wipe and then restore all my app, now my phone stay alive double of time before the full wipe, and on the morning not lose anymore the 10% of charge.
[Droid Incredible General] sshafranko:
What do you use to backup and restore? Titanium?

No, I use 3cToolbox, are an all-in-one for backup, restore, change kernel setting and other stuff, for app I can restore app+data or only app.

Hey guys as u can see the ss m getting some sudden drops this usually happens after 30% while screen is off i did try to calibrate my battery 3-4 times but it didn't help anything else i can try?
[Droid Incredible General] JimmyRay:
Great read, thank you for the clear explanation!

As this article was written over five years ago, I'm wondering if there have been any changes in battery technology, or the way batteries are monitored in Android/CM?

By the way, I was informed of this thread after querying the 10% drop from full-charge in this post. While I certainly appreciate the detailed explanation, I have seen battery usage screenshots from some users showing a steady decline from full charge - is this simply a case of different phones (OSs?) implementing varying battery monitoring techniques?

Thanks again!

2) reboot phone

3) go to apps and clear the download manager

4) log into Google talk & sign out sign in etc

5) force close market

i had the issue. I basically had to stop all apps from updating, and do them one by one and even then it was a pain. You may need to just try a few times. Everytime I hit update all, thats when I have the issue. I just do it the old school way one by one, and keep trying if it dont work. Lol

Odd, but I had this issue yesterday when trying another new rom.

What I did was immediately after accepting the permissions and being brought back to the My Apps/Download screen where it shows all the apps, was to IMMEDIATELY click right back on the app....

for some unknown reason this was the only way I was able to update about 5 apps yesterday... never had an issue before.

Clearing the market data is also a popular fix as previously mentioned.

If someone can try my method I would be curious to hear feedback... I was amazed this worked its so simple/odd.

I know the Samsung equivalent to HTC's "tri-color boot screen" is called "Emergancy Mode," so perhaps that is what he means.

If you see a three color screen with "SPL" information, simply attempt to flash a shipped rom for your carrier, so long as the SPL does not have "coke" written in it. can you post a picture of the screen? If you already unlocked it, simply try to flash a 3rd party rom.
