Does anyone have any ideas on how to increase car charger performance?
When I am using Google Maps Navigation with the GPS running and full 3G signal, the phone barely charges at all. Depending on screen brightness it can actually drain the battery(slower than when not connected to a charger).
Can the charger be modified to increase its output?
You have to buy a charger, which has more than 1 ampere
I have the Brodit Active Holder w/ Cig charger, I'll have to check the specs on it later. Do you think it could be modified in some way?
I bought the SE car charger (http://bit.ly/k7udKw), the price was a bit steep (20 euros or so) but it works like a charm. I use Sygic Aura navigation and the battery meter still increases over time. Not fast, but it doesn't stay put or decrease either, so I'm all in all happy with it.

And make sure you set your phone dock near the air conditional if you open GPS map, it'll get hot and your battery won't last long while it gets hotter even you charge it.
I bought my charger on Internet auction for about 2 Euros (some crappy China stuff) It works like a charm. And yes, battery gets very hot when I use navigation so I mount my phone holder near AC vents.
There must be a reason for the severe heat in the x10.
even in ultra low temperatures it overheats a lot.
So i finally remembered to check my car charger and it is a 1amp charger. I've just upgraded my rom to the one listed in my sig and the phone is much better on battery, so hopefully it charges better in the car now.
Had my phone docked in the car for 20minutes and it charged from 82% to 95% with the GPS on and Google Maps following my route. Pretty happy with that sort of performance.
Mines charge normally i use orginal se charger because in my car i got an ac plug
Sent From My X10!
im using this one
http://www.amazon.com/AT-BlackBerry..._1_1?s=wireless&ie=UTF8&qid=1310226373&sr=1-1
it charge fast and it can charge another USB device like an iphone or my MW600 bluetooth... it can even charge my x10 to 100% while GPS navigation is on. my previous car charge doesnt do that, it can only hold my battery % without letting it drop if GPS navigation is on. so if my battery is 30% i'll get 30% after i disconnect and stop using the GPS navigation...

I've bought this one a while ago for 7 bucks (including shipping). Had just a few chances to use it, but all times it was really sunny and hot outside and the phone just stops charging because it becomes extremely hot. I would stick the mount somewhere near the gear stick, but it won't stay on any other surface than glass
It was a quite funny adventure when we were travelling to a big city with intense traffic and really complicated streets. So I am using the GPS to find the hotel we booked, it's really hot, I just keep going - didn't know that the phone stops charging when it's hot - so we finally arrive at our destination, I start to reach the phone with my hand and it just turns off, because the battery is dead. Was quite scary at the moment
Yeah, did some driving around this weekend using Google Maps Navigation. Had my X10 plugged into the charger that came with my Jabra Cruiser speakerphone. Despite the charging light being on the whole time, by the time I arrived at my destination my phone had >5% battery. I checked the charger, and it's only 500mA.
Ordered this charger from Monoprice.com (was ordering some cables anyway). The price was good, and specs say it outputs 1A. Will let you know how it works out when I get it.
Hi,
I'm having an annoying issue with my car charger. I'm actually using the SE car charger, the 1200mA one.
The problem is that sometime, the charger will charge very well, meaning I can listen to music, have the navigation active, and twitter, G+ updating as usual, the battery is charging around 1% per minute, but on other time, the battery will slowly drain, same setup.
I've noticed something yesterday btw, the phone was in a battery draining phase, then it appears that the phone lost his network connection, then it came back, and the phone started to charge well.
Is that an issue related to the car charger or could it be a "bug" in the phone software ?

The phone limits the charging current at a max of about 700mA.
Sometimes the radio eats thru the battery quite heavily in low signal area's.
The charging current just plainly cannot keep up with the total usage.

Thanks for your fast answer.
Maybe updating the baseband (actually i'm using the 2.0.46) could help ?

You can try that.
In some cases it works in other cases it does not.
I have had my X10 for nearly 2 years now and i have tried about 5 different car chargers until finally settling on a SE original.
I use my x10 with google nav all day long as i am a service engineer and i have found the only way to get it to work for a full day is to mount it directly infront of one of the air vents blowing cold air over it while plugged in to the charger. Without this the phone will get too hot and start discharging especially on a warm day.
Using 2g and low brightness can help as well.

LOL. The X10 was released in late March 2010. So unless you had an early development model, you've had your X10 for 16 months at most.

Yeah, I learned how crazy heat will build up in this phone if using it for nav a few weeks back, when in about 75 minutes of driving I drained my battery fully and the phone was registering at 54°C from sitting on my sun-beaten dash while navigating.
I thinking I'm going to try to build some sort of shade over my car holder to keep the X10 out of the sun, and maybe help channel some of the AC more directly onto it.
Forgive me if this has already been discussed or is supposed to be common knowledge, but is the GPS supposed to eat up all of the electricity being conducted by the charger? I am running stock everything with nothing but some basic services and have not seen 1% increase on my battery in 3hrs of being charged. I know the charger is not the issue. I used my car and Mac Book Pro with no change.

It comes down to a few things. I can't say for sure if it has this same affect on car chargers (I can't see why it wouldn't) but when I used my Motorola wall charger with an aftermarket micro-USB cable, I saw extremely diminished current reaching the battery. Just using the phone with brightness on max pretty much counteracted any charging I was getting from the outlet and at some points I was even seeing the battery DRAIN much like you are.
That being said, GPS is extremely taxing on the battery. When you combine that constant GPS lock with data streaming over 3G, along with the heat of sitting in sunlight in your car, well it takes a toll on the battery. Assuming you're using the proper car charger designed for the Thunderbolt and the proper cable, well then there's nothing else that can be done. It's a game of current in vs current out. I know for a fact that just by using the 3G data connection with screen brightness on max my battery draws roughly 400mAh. Add in a GPS lock and extra heat and that can easily reach 600+. Your car charger has to send more than 700mA to the phone in order to gain charge and not just break even.
I'm having issues with this too, but I found a thread in the accessories forum about a rapid charger from Motorola that seems to work for our TB even with GPS use.
http://goo.gl/gAIGV
I ordered it and should have it soon. Hopefully, it'll solve this problem.
I travelled from the midwest to the west coast on vacation driving in my car a couple of weeks ago. Used my phone for both GPS and Pandora (surprisingly great 3g coverage across half the country).
Had the phone plugged into a 3rd party generic charger all the way and never once had an issue with phone not charging.

Did you happen to notice if Google Maps was eating a larger percentage of your battery? Mine recorded a 46% screen and 37% Maps usage. (I left it unplugged for about 5 min. With the screen on while reading the XDA)

Yeah I figured it would be like that, but what didn't make since I was able to charge an iPad with my Mac while it was in use. With a little Google[ing], I found that my thunderbolt was only drawing the 500 mah. I then found that the iPad does some voodoo and receives an extra bundle of 500 mah. Now... how to tap into this?
Edit: For the car charger, it looks like someone over at the Android Forums forum explains what needs to be done well. http://androidforums.com/incredible-accessories/171716-car-charger-explaination-sollution.html

Sorry, did not keep track of the usage, but I do know that my phone did not run hot at all (which is usually a sign of extreme power drain while charging).

There seems to be a debate on this topic as to whether you should do a FULL drain on your battery and I wanted to know what people's thoughts were on this in this forum.
I've used my phone twice now to the point where it has auto powered down on it's own. I will then hit the 'Power' button to ensure that battery is truly at 0% (the capacitative buttons blink for a second to confirm that I've hit the power button but there is no more juice left to turn the phone on).
I will plug into the wall charger and allow it to charge for 4 hours (usually around 4 hours, I'll check back to see and hit the power button and the onscreen battery display will show 100% charged).
I will unplug my phone, power on and keep using until the phone fully drains and powers off on it's own again before repeating this cycle.
However, others have stated that this is NOT necessary for Lithium Ion battery and can actually damage the circuitry of the battery? I've always been under the impression that you need to do a complete & full battery drain for lithium ion batteries at least 3 -5 full cycles/times before the battery has been conditioned/optimized for capacity.
Maybe I'm wrong...after all I'm coming from a G1 and this practice helped my atrocious battery life on that dinosaur!
If this is wrong, when should I be plugging my phone back in to charge? When it gives me the first warning to charge in (battery level turns orange - I assume this about 20% battery left) or on the "critical" battery warning when the battery icon in the notification panel turns red (assuming this is about 10% battery left)?
from what I've read in the past, letting your phone drain completely down until it shuts itself off is not good for the battery. I could be wrong but thats what I've read

Yeah, I've heard both sides and I've conditioned my battery for the G1 because it seemed to drain faster if I plugged it into charge when there was 30% or so still left.
Well, I've done two complete cycles so I guess I'll just try recharging when it hits the red mark next time.
When you plug in to charge? Orange, red or whenever to top off?
i plug my phone in when i go to bed. I dont care what the battery is at. I also charge it while i'm at work so when I leave, its around 90-100%. My battery rarely reaches red.

LOL - that would prematurely killed my battery capacity on the G1! I went thru two batteries before I started draining all the way down. Made a difference between 4-6 hours and 6-10 hours.
Seems like this phone doesn't need to do that tho.
But what're you getting on average for battery life and display on time then?

I do the exact same thing. First with my Captivate and now with the SGS2 and the battery life on my captivate held pretty much exactly the same charge for the entire 15 months I used it. The battery on this SGS2 seems to last about 150-175% of the Captivate battery under the same conditions. I just came back from a week on the road where I spent 9-12 hours a day away from a charger and was using my phone constantly all day long and would get back to the hotel room with 30-40% battery left. Considering I was listening to music, playing plants vs zombies and sending and reading push email constantly throughout the day I am very satisfied with the battery life on this phone. I've never done any kind of conditioning or special battery maintenance.

i stopped looking at my battery stats a long time ago. I'll peak in there once in a while but I dont really care what the stats show because I'm always around a charger. As long as I get through 12 hours or so without charging, i'm happy.
Some devices need a full drain cycle to properly calibrate the fuel gauge - ours does NOT.
Lithium ion batteries don't like deep discharging - in fact discharging them too much will permanently damage them (fortunately, all batteries sold to end users have built-in protection chips to prevent overdischarge - but do you REALLY want to rely on that chip?)
Similarly, they don't like charge being forced into them - so don't "bump charge". (Bump charging is removing and immediately reinserting the charger when the phone says charging is complete.)
For long-term storage, store them at around 50% capacity if not being used. LiIons that are stored at 100% charge lose capacity MUCH faster than ones stored at 50%.
A Li-Ion that has been sitting for a long time (months...) will develop a passivation layer that can be detrimental to performance - a few charge/discharge cycles will fix this. You don't need to do a full discharge/recharge - probably even from 90 to 70 and back up a few times should be fine.

what about short charging during the course of the day? For instance, while I'm at work, I like to plug it in for a bit and then use it off the charger. Then before I leave, I charge it again for a bit. Do you think thats okay to charge the phone for short ~1 hour bursts?
No, the battery itself doesn't do well with deep discharges, but every device with one has circuitry to manage this and keep it from happening. The phone will shut off before the battery reaches a critically low discharge state. Just as it will cease charging before it blows up. Just because the phone shuts off does not mean that the battery is too low.
Assuming the phone has the proper cutoffs, it's not really any different to do two discharges to 50% or one to 100%. There have been studies that say leaving it on a charger is bad, doing two 50% cycles is worse than one 100%, etc. I've always just trusted that the phone manufacturers design the battery monitor and control circuits correctly and not worry much about it. And I've never had to replace a battery yet and always get acceptable life.
It's lithium ion, not nickel cadmium.
Full drains are bad for lithium ion.

lithium ion batteries dont like being under 30%. and they also dont do well if they are kept at 80 percent or above all the time. for longest battery life don't just let it sit on the charger all day after it fully charges.
I agree with Mikey here.
Also, batteries take charging current better (less wear) at lower states of charge. That's why I put a variable-current charging algorithm into my Infuse kernels (charginghacks branch on github)
800 mA at low voltages (200 above stock), dropping to 550 near the end (50 below stock).
Unfortunately, charginghacks is likely not going to be possible with our hardware. One of the differences between the I9100 and I777 is a different battery charger circuit - ours is far less flexible.

This phone actually charges with the screen on though, so it's not like the Infuse where the battery would drain with the screen on and the phone charging.

Infuse would charge with the screen on - but not if the screen was on AND the CPU was cranking.
(worst-case was navigation at full brightness - and I've seen reports that the I9100 also has the same problem.)

When web browsing, playing a game, or other general use late at night I'd plug the Infuse into the charger. It would still drain. Doing the same on the SGS II and it at the very least maintains it's battery level, so it's a drastic improvement over the Infuse.
I've had my new HTC Amaze 4G for 4 days now and absolutely love it, what a great phone! The battery life is great (I'm careful with all my settings) and I'm only finding issues with the charging TIME.
It's the second time I've charged it and after noticing how excessively long it took the first time, I clocked it this time and it took 4 hours and 45 minutes. I used a charger that I've used on many other devices with no issues (5 volts 1 amp).
The battery level increases 1% every 3 minutes, which adds up to 5 hours. I calculated this both with the screen on and by averaging out over a longer period of time with the screen off. I also tried with the phone completely off and the results were the same.
I made sure there were no processes hogging up processor time or excessive RAM usage.
When I go into to "Settings -> About Phone -> Battery" Battery status clearly states: Charging (AC).
I have also read somewhere that this can possibly be set this way by design (possibly to prevent the battery from heating or overcharging and saving its life in the long run).
I also realize that the phone is new, and the battery needs a few charges to be settled, but 5 hours to charge on the second charge just seems like too much.
On the HTC product support website, on the faq there is the following question/answer:
How long should it take to charge my battery?
"Your battery can take up to 4 hours to fully charge using the AC charger. It will take much longer using the USB as that is the trickle charge function."
Can anyone out there with an HTC Amaze 4G confirm how long their phone takes to fully charge from the AC charger?
I'm thinking/hoping this is a defective device/battery/setting...I don't like having to wait 5 hours to have my phone fully charged.
Thanks in advance,
Filipe
Ok, I'd like to add one more thing. I finished charging the phone last night (about midnight), by the time I went to bed (around 2 am), after barely having used it, it was still at 100%, now at 9:30 am (7.5 hours later) the battery level is at 95%. I had everything off and very little background services and apps running. Even the network type, is only set to the basic, no data connection was live/standby.When I check the battery status/histogram this is what I get:
-44% went to Cell Standby
-42% to Phone Idle
-8% Display
-6% Wifi (I think I used it before I went to bed, but turned it off right then, and it remained at 100% battery)
I'm not too happy...this can't be right...it shouldn't take 5 hours to charge and discharge this fast? Can anyone shed some light please?
Thanks
Come on....anyone? Please? This is driving me nuts!!
Yeah that sounds about right. Don't complain man. Your battery life is pretty good compared to other devices. My device takes 3 hours to fully charge and can last 24 hours with minor use. Just charge it when you go to bed and you won't notice the time it takes
My desire hd takes almost as much (Around 3 hours) and my Optimus 3d prolly takes even more (5?) to fully charge from a full discharge...
(With Stock HTC/LG Charger. The HTC's AC Adapter is 5V/1A [Shouldn't that charge a battery in under 1 1/2 hrs?]. Not too sure about the LG)
They take Much longer to charge on Computer/Laptop USB Ports. The Optimus 3d actually loses battery while charging (With screen on) with a USB port.
Also, 5% a night is pretty good. My desire hd goes down 3-5% per night (2g, no data enabled.) or 0-1% with Airplane Mode. (Rooted, Revolution 6.31)
And my optimus 3d pretty much runs out of battery in <100 mins with full brightness while Playing Games - It goes down more than 1% per minute depending on the game being played, especially if 3d Converter is used. This is pretty much the same for all GB/Froyo ROMs.
Just charge it when you go to bed and you won't notice the time it takes

I Agree. Both phones usually last around a day at least for me. You could always try a battery monitor such as GB Battery Stats or watchdog (The CPU One). CPU Intensive applications and Awake time during sleep are usually what cause bad battery life. Faster chargers such as 2A ones should also charge the battery faster, but they might reduce the overall battery life.
I would suggest buying a wall charger and cheap batteries from ebay. They last almost as long as stock batteries and cost only ~$2-4 each. [They apparently explode though. Never happened to me.]
-------------------------------
Both phones seem to charge from 0-90% much faster than 91-100% as well. I'm not sure why, since 100-90 wastes just as fast as 90-0. (Charging from 90%-100% battery practically takes a third of the full charging time)
many thanks
RESOLVED (Sort of...lol)
Thanks for your feedback guys!
I just finished charging it this morning, and it's FASTER NOW!
Took exactly 2 hours and 37 minutes (Battery Moniter is a great app!).
I think it actually may be due to the phone having some sort of smart charging system which "looks after" the battery. Since the phone is new, it might be wanting to start it off with some slowww charges and gradually speed them up.
But I still have to narrow it down some more since this time I'm actually using the supplied cable and charger (the ones I tried before were also 5V/1A).
The cable I was using (had it for a while now) had a pinch or two, it didn't look that bad, but I'm thinking it could also be the cable (could be shorting)!
I'm gonna do some testing on this cable now and report back my findings!
Thanks again!
RESOLVED!!!
Ok, so it actually turned out to be the cable. I really feel like a dumb ass...lol. Oh well, at least I figured it out!
So yeah, one good way to see if your cable / charger is good is to use Battery Monitor, and on the main screen where it says your device is charging (AC) and etc..it will also say the actual amperage (in mA) being fed to the battery...that number should be within the 500 to 750 range, if its lower, there is likely something wrong. (Mine was at 16...lol).
Thank you all for your help!!
Cheers!
can you explain to me more !!! i just had the phone and the battary run out like 5 hrs after ,,, what s about your cable-charger problem i didn t get your point !!! can you help me plz

My problem was the cable, and it was causing the phone to take five hours to CHARGE, not discharge.
These phones don't hold charge for too long, and the more activity you got going on, the more power it will consume. The screen hogs up the most power, so using the device constantly (especially with high intensity background light) will drain the battery very quick. First smart move would be to set the screen intensity to the lowest setting. Wi-fi and bluetooth, if you're not using them, shut them off. Open your task manager (or get a decent one from the market) and kill all the apps you got running in the background.
Games also require a lot of graphics/processing power, so naturally they will drain a lot of battery too.
Edit: There are some special cases where it could also be related to your network or even simply coverage zones exposed to the device. If it's stuck in a zone where it has weak 4g and 3g signals, it will keep bouncing back and forth causing more drain than normal on the battery as well.
If you've taken all these things into account, then you may have a defective device, then you will want to setup an RMA...or just take it back wherever you bought it and ask to exchange.
Hope this helps,
Cheers
My skyrocket takes about 3.5 hours to charge from 10% to full charge. If I plugged it in the car charger and run google map with the radio on the background, it would slowly drain the battery even though it was plugged in. My iphone 4 did not do this. It charges very fast and does not drain the battery even when I had several apps running in the background. I think the skyrocket consumes more power whether it is plugged in or not.

Hi, what you need is a charger with a higher amperage rating than 500mA (or 0.5A). Buy a charger that is rated for 5V/1Amp like this one and your problems should go away.
The phone is basically "burning" more energy than it is receiving from the USB charger, hence the discharge.
To know the amperage rating of your charger look on the label for numbers that look like "5V/500mA"...
Hope this helps,
Cheers
EDIT: The link I provided does include an iPhone cable, but I'm just referring to the charger itself, the cable would obviously have to be a micro-usb.

thread moved to...mexico?
Most illegal threads are trying to move from Mexico.
But, you need a charging source more powerful then the base 500ma, (or whatever that term of measurement is) computers are only supposed to supply 500ma to a USB port so AC adapters are typically better for charging. But feel free to follow the post above and check the rating on the charger.

i just got my amaze, and i have auto sync off and screen on dim and it still takes for everrrrrrr to charge.. ive used a few different chargers and cords but i just got the phone so maybe after a few charges it will speed up? not sure my mytouch 4g never took this long although it would get verrrry hot

Well the amaze does have a hefty battery, mine is charging a bit faster than when I first had it

Make sure to use the original charger and cable that was supplied to you by T-Mobile/HTC
I noticed the 12-pin cable is faster than the 5-pin.

Ok, I'd like to add one more thing. I finished charging the phone last night (about midnight), by the time I went to bed (around 2 am), after barely having used it, it was still at 100%, now at 9:30 am (7.5 hours later) the battery level is at 95%. I had everything off and very little background services and apps running. Even the network type, is only set to the basic, no data connection was live/standby.When I check the battery status/histogram this is what I get:
-44% went to Cell Standby
-42% to Phone Idle
-8% Display
-6% Wifi (I think I used it before I went to bed, but turned it off right then, and it remained at 100% battery)
I'm not too happy...this can't be right...it shouldn't take 5 hours to charge and discharge this fast? Can anyone shed some light please?
Thanks

Sounds about right. If you want better battery life either root it or buy another battery.
To get really good battery life ?...you got the wrong phone man.

unplugged my phone at 8 read xda forum for 5 mins got to work right now 943 already at 89 percent. Does this seem normal? I been checking better battery stats but don't really understand it. I feel like something is trying to sync. i have fetch off for email and Facebook. anyway to diagnose this on saurom rc4 clean boot.

Are you overclocked? If you are, which governor are you using? I've posted in the OC kernel thread about an issue where the CPU is running at max frequency the entire time causing a huge battery drain.
I am right now but its showing me deep sleep and 192mhz on demond has a big percentage. Its not running max clocked i know that.

This is my shots I'm at 78 percent now been on xda for maybe teen more mins. My brightness is one step above min level. Its like 1 percent every 3 mins when screen is on even if I'm idle.

I think I know what the problem is: Your phone is trying to kill itself and save humanity from that terrible font
seems like a bit much but it could be normal.
Once your phone's charge reaches 100% it stops charging to prevent damage to the Lithium-ion battery. I am not sure however when it starts charging again.
Mine charge % dips even when I am using plugged in! Horrible consumption with screen on.
installed only few apps.

Are you using the Samsung OEM home charger? It shouldn't be dipping when using that one. Mine will charge AND increase while using it in the car with GPS running (huge battery drainer) and a driving DVR program (DailyRoads Voyager) and the screen on. All with a car charger and cheater plug that shorts Pin 2&3. That's the secret to getting rapid charge to work. The OEM home charger has those pins shorted internally. If you are trying to charge over USB on your computer then again you need that cheater plug and ensure the USB port can support more than 700 mA. If it's a USB 3.0 port then it should handle that current.
No problems for me on the stock or aftermarket chargers with the screen on.
I have the same problem with my brand new I717 GN. Battery level slowly drops when on charge, even if it's the OEM wall adapter. I've tried my Kindle USB cables as well with about the same results. I noticed the charge is a bit stronger from the wall source, but still can't keep up with even simple web browsing via WiFi. I've installed JuiceDefender as well, and it's helped reduce depletion a bit, but not really enough. This phone would never last me a full day of intermittent use without a power source.
I've read several of these threads and there doesn't really seem to be a solid solution to this other than some GN owners saying they have the problem and some don't...
Someone mentioned a crosswired 'Smart Adapter Compatible with Samsung Galaxy S' on Amazon (I'm too new and can't post the link)... I might try that but maybe I'll return for a new one if some people don't have this battery problem, unless it turns out to be a latest firmware problem..?

he mentioned it and linked it 2 posts above you
ive thanked him, and guess about to buy
just that shipping cost more than the item itself, sheesh
I read an article in a journal recently about how smartphones charge their batteries. The article claimed that once the charge has reached 100%, it will stop providing current to the device until it reaches 90%, after which it will then trickle charge to maintain it at about 90%. All the while the battery meter will still show 100% (at least in the case of iPhones), but after you unplug the phone the first 10% will go rather quickly as it approaches the real charge level.
True for our notes? No idea. But with how Lithium batteries work, I wouldn't be surprised.
I haven't gotten my Note to discharge while plugged in with the OEM AC charger. In the car however, running Waze will suck the life out of it even while charging. (My car charger puts out about 150mA less than the OEM AC charger). Oddly enough, running Navigon on battery alone has less discharge than running Waze while plugged in...Which sucks, because while Waze has crappy directions, it has saved me many hours by routing around traffic. But at least the phone still charges while using Navigon and streaming some Pandora.
