Is it possible to connect charger without battery so that i can use device all day and avoid over-charge or possible battery damage?
Beautiful just Beautiful
Guys i have another one for all of you
"Is there a way that i can use my Phone without connection so that i will have no bill charges ?"
Batteries in Tornado can (even should) be charged often Don't worry about it
Yeah, over-charging is no problem. It'll stop charging when it's full.
This does raise an interesting question, one I haven't really bothered to try but have just now become curious about. Can you plug the phone into the wall, sans battery, and use the phone still? Or will it only function, plugged in or not, with the battery installed?
Phone turns off when you get battery out :/

LOL, I just tried that last night, and... ohh Noo it don't even turn the power light on w/o a battery... so @Amaric: Keep charging it!
I am aware that phone is not working if you take out the battery and connect it to a charger. I was wondering if there is some kind of a workaround.
My plan was to have phone switched on for months with wireles ON too. That just can't be good for battery and it could even be dangerous.

Turn off power savings on Wi-Fi and leave phone ON, doing something over the internet, just idling, so that the LCD is off. Say for example: acting as router.
Conditions:
1. Phone w/full battery -
2. Phone charging w/full battery -
How long did he battery last? How did the phone temperature change? What would you guess would happen in 48hrs of usage?
EDIT: My experience with Wi-Fi is that it drains more power than the charger output. Temperature raises substantianlly w/o LCD, gets extreamly hot w/LCD on. So what would be the options?

Is this a joke? If not, then some change to a software (OS) could do the trick.

my opinion? If it does stay on after removing the battery, then it'll do the same if you have the phone on while running Windows, and charging and remove the battery. Battery charging is not handled by OS, its handled by Hardware.

Does anyone else think this is true? I think it would be unlikely that having the screen off but wifi on would use more power than the wall adapter provides.
I suspect that you could jumper the battery connections to mimic a full battery, but I am not going to try.
I think you can put resistors to mimic the internal resistance of a battery, but I wouldn't recommend it. If anything goes wrong you might burn out the charging/power control circuit which probably would turn your phone to a brick.
Oh, and the whether it charges when plugged in and using WiFi depends on your charger. I've got a 6V 2.4A (15W) charger for my phone, good luck using up all that juice with a Tornado. That thing easily charges my TyTN with HSDPA (3G), WiFi, Bluetooth and screen active.
15W is more or less what my laptop uses under normal load
Hello everybody, I own an HD2 that is alway connected to a table cradle (connected via USB to a PC) during the day when I'm in Office. I wonder if exist an app that allows to manage the battery charging: I explain...I'd like that the HD2 AUTOMATICALLY "turns off" the charging when the battery is fully charged at 100% and automatically "turns it on" again when the battery charge reaches a given threshold (60-50-40% or something like that). If you own an IBM/Lenovo Laptop I'd like something like the power managment app. Of course the data syncronization HAVE ALWAYS TO STAY TURNED ON regardless the chargin of the battery.
Does it exist somehing like that?
Thanks and regard
Andrea
There is a setting that allows for the battery not to recharge when connected to a PC. Other than that, I completely fail to see what would be the purpose of what you are asking.

thanks for your answer! I already know the setting you're talking about, but as I told early I'd like something that manages this setting automatically. The purpose is to avoid the decreasing of the battery lifetime caused by letting the battery itself "always" connected to a charging source. For example in the Laptop PCs it's better to unplug the battery when the laptop is conncted to an external power source/charging unit...
Thanks

Most modern devices (and, I believe the HD2) actually disconnect charging when the battery is at 100%. The green light doesn't mean that your HD2 is still charging, but that it's at 100%. Therefore I don't believe you actually shorten the battery life by keeping it plugged in.

I did believe it too but I have an app wich monitors the battery temperature and still when the battery charge is 100% its temperature remains "high" (35 grades degrees) as long as I keep the device plugged to the cradle. I see the same temperature value when the battery is actually charging...this fact have made me change my mind about the fact that the HD2 disconnect charghing when 100% is reached...
Its not the battery which is getting hot, it's the phone.
If I had a lithium-poly/ion battery that was reaching 35C I'd be very worried!
If your app is showing the battery at 35C, turn the phone off, remove the battery and it should be cool to the touch.
If it's hot then you have a problem.

Heat will decrease the life expectancy of the battery, but so will deep charging rather than top ups, remember with non-NiCd batteries you don't get memory effect, so the only reason to do a deep charge is to recalibrate the software battery meter.
Of course leaving the battery sitting on a shelf will also degrade it's capacity, they start to degrade as soon as they're produced, so buying a spare and not using it until your original battery dies is not a good idea, better to buy a replacement battery when the original starts failing.
HTC's batteries actually seem very reasonably priced too which is refreshing.
Do you only use the HTC charger that came with your phone? MicroUSB is MicroUSB and it will charge from any charger BUT I have heard that different milliamp chargers can cause undesired effects in the battery (of any phone) such as decreased lifespan or less battery life in the short term. Any truth to this? Only reason I ask is because A) I'm curious and B) I got my Sensation yesterday, charged it with the stock charger at work but left it by mistake. When I got home, I charged it with another charger I had lying around. After 8 hrs off the charger, I had dropped from 100% to 99% (awesome). I then made a phone call this morning for 6m and used the display for 15m and it dropped to 94%. I then left it in my pocket for another hour and it dropped to 90%. I don't get it! :-(
Two separate issues here:

The official HTC charger is 5V 1A. Some other chargers, such as car lighter chargers and USB ports only give out 0.5A, so charging takes much, much longer. In fact, if you use a 5V 0.5A charger whilst continuously using the phone for something battery-intensive like sat-nav, the charge will still drop, but not as fast as if it were not charging at all. You'll get a warning on the phone something along the lines of "the charger is not sufficient to charge the phone and use it at the same time" (can't remember the exact wording). make sure you use 5V 1A.

This much I know. But they aren't all 1a. My old Defy charger was like .8 and this is 1a. I'm not referring to charge times. I pointed out your GPS point to an OP in another thread. I'm referring to if using a different MA charger effects the quality of the battery or how long it can run on a charge.

Conclusions?
How many amps can one charge at?
I see car charger product that claim to output at 1a, 2.1a, even 5a.
Then I see that it may not matter what the output of the device is: that unless the cable you use to charge shorts the center two pins together, you will only get .5a.
Bump.......
I've always understood that a "trickle charge" or a slower charge is better. I only charge via usb for this reason. It takes much longer to charge, but supposedly it charges the battery in a better way and it will discharge slower.
Any truth to the battery conditioning tips I've seen about letting the battery charge and drain 3 times completely when new? I have read that these lithium batteries dont require that but I keep seeing conflicting info.

In addition to that, I'm curious on how you all charged your phone the first time. I want to make sure that I do it right when I get my Sensation.
So where are these battery drain threads?

I used the wall charger initially but then switched to USB which actually seemed to work faster. I used my N1 charger earlier.
Anyone going to advise on battery drain? Losing 4-5%/hr idle. No, it isn't an app.

Because I had no apps installed that would do that, there is nothing in battery use, etc. 2%/hour is high for the sensation.

There are apps and processes that are part of the system that can drain power like that. Having a bad signal and constantly dropping connections can run down your battery. Did you pick up watchdog for free on amazon yesterday? That can tell you more about what is using the cpu.

Well that's okay then. I was stupid enough to think you might have used something such as System Panel or Current Widget from the Market to actually verify the battery drain and the tasks/apps that were responsible.

High? My HTC Desire drained 1.75% per hour with CM7, so 2% for a dual-core phone running HTC Sense is pretty impressive, IMHO.

If you read up on the reviews, you will see that the Sensation has achieved <1%/hr drain with items syncing.
Im really anal and I dont open my phones accessories if I dont have to lol. I have been using a spare MT4G charger and its working fine. It is rated at 1 Amp like the factory Sensation charger is though.
For those wondering, as slow as these batteries discharge you will probably not see any gains in performance when you trickle charge a battery (for example over USB) over using the stock charger. It is recommended you fully charge the battery and fully discharge it the first time you use it. The battery life will get better after a couple cycles, yes they need to be "broken in". Like all rechargeable batteries they will degrade over time, it is inevitable. Since OEM batteries are so cheap these days I personally dont go too far out of my way to "properly" charge and discharge my battery. It will die when it dies, at that time I will just buy a new battery.
I have gone through about 3 cycles if battery, with fast charging turned on. Battery life has not been good, especially with screen off drain. Getting about 3hrs SOT while I've heard people say theu get around 6.
So my question is how many cycles should I go through before I judge battery? And should I disable fast charging? Does fast charging damage the battery?
I have the verizon US variant, so there isn't much I can do to improve battery life without root...
Thanks
Turn fast charge off. Turn off AOD. I have an AT&T model. Helped my battery immensely....
I can go the entire day, 6am to 11pm, with average usage and have about 40% battery left. VR drains my battery like butter on a stove.

I'm also on VZW and I've had my S7 for a week. After about 3 days of poor battery life (~2hrs SOT), I turned AOD, location, BT, and NFC off, and disabled a bunch of bloatware (I posted what I did in the battery thread). That improved my SOT to over 4 hours +more standby time. I've since re-enabled BT and location and haven't noticed a difference. I left fast charge on but I use a slow charger at night, just because that's what's plugged up behind my bed.
Sorry, I don't have a source but I'm pretty sure I read something credible that said fast charging doesn't affect battery life/quality. I know that's pretty flaky, so take if with a grain of salt because plenty of other people are saying it helps.

Fast charge doesn't affect battery life immediately, charging your phone faster causes heating and overworking of battery, so slowly, average battery life decreases.
Slow charge when possible! (Wireless charge generally heats more than wall charge!)
... My 2 cents
My phone on fast charging, even wireless doesn't get any hotter than previous phones. My other half has a HTC One M8 for two years and still gets 5-6 hours SOT and has fast charged since day one.
I use fast wireless charging and get 6 hours SOT.
All I turned off is NFC, and my signal is usually full.

So, to slow charge a S7, do we have to turn off fast charging from the settings and then charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?
Does this hold true for Motorola's phone also which have turbo charging option?
Also how to measure battery cycles? Any credible app for the same?
Just turning off fast charge you do a lot good for your mobile..
One thing you can do is check battery temperature as you change charger or method. I don't know about Motorola, but maybe its battery is user replaceable... I personally don't know any app that keeps track of battery temperature

Thanks for replying. I wasn't able to find any battery cycle file/log in that location, quite strange. And yes I have the Exynos version. I will test your app and will get back to you.
Of the little what I have understood from various threads here is to charge the battery when it is between 20-40% to 80-90% if you want to have a good battery life. I used to do the complete opposite charge, when the battery is at say 6-7% and charge it till it is maxed. I used to do the same for my laptop, any other tip for the battery?

Can anyone help and give me tips on how to stop my screen and mobile standby using so much battery,, also im using official moto charger and getting 7 hours until fully charged without any apps running, am i doing something wrong here
Thanks :good:
Mobile Standby is based on cellular signal strength, the better the signal the lower the battery usage, in general.
Screen should be the primary battery user, but you didn't give us a screenshot of your screen on time to make a fair comparison if it's normal or not.
The charge time is messed up though, mine takes less than 2 hours from under 10% to full if left idle, try another cable or charger with 1.2+ amp supply and check the USB port for lint buildup, I have seen excessive pocket lint build up and keep the cable from making a good connection.

Unfortunately, that screenshot doesn't tell us much because you have been charging partially off and on (statistics are since the last full charge), but I think your statistics are off... they add up to way more than 100% in the first screen shot, but I would expect the screen usage is normal since you are using the device quite a bit. The only way to get the screen to use less power is to turn the brightness down, otherwise that is one is and should be the largest battery user.
And even without a SIM the device will still look for mobile signal, it is capable of making emergency calls and to my knowledge in the stock ROM that cannot be turned off.
Thanks for the reply, sorted the charging time problrem out and lowered the brightness down to 10% and im still getting alot of usage also just to clarify i cant really do anything over the screen consumption?? Thanks :highfive:
New moto G 3rd Gen in the household. Is it not unusual for the shipped charger to struggle to charge at all when screen is full bright and wifi all radios are active? My son reported the phone would not charge at all. eventually went flat and had to use the Vol-DN/Power combo to revive it for him. Seems to be charging fine now with the supplied charged with the handset powered off. I suspect he had overwhelmed the charge by pegging everything full bright and on. Is this about right for this phone?

Sadly, this isn't unheard of... The charger that comes with these in the box is garbage in some parts of the world, check the rating on it, if it's under 1A/1000ma get a decent aftermarket one rated at 1.5A or better.
Sent from my Motorola XT1575 using XDA Labs
Thanks. Good advice the supplied charger is only 850ma. Will get a more powerful one.
I also wonder if the battery charging has some conditioning login going on in the first few cycles.
Last night I observed this weird behaviour as the phone charges.
-Motorola SPN5512A Phone USB AC Charger Power Supply 5.1V 850mA.
-Phone off.
-Pressing power button intermittently to display battery graphic and charge level.
It charges fine to somewhere over 51% and then begins to discharge rapidly whilst phone is off and charger is connected !!
At this point the screen remains on with charge indicator permanently displayed. Phone is still switched off.
This is a log of how it was charging, with me doing a quick press of power button to read the level.
5:24pm 35%
5:34pm 41%
5:46pm 48%
5:56pm 51%
<- In this period phone which is still powered off, spontaneously begins to discharge
7:20pm 30% screen on and battery icon displayed permanently. Phone is still off though. pulled charger and re inserted @ 7:21pm
7:31pm 36% now charging again with screen going off and the need to press power button to see charge indicator.
7:36pm 39%
7:45pm 44%
7:55pm 50%
8:17pm 62%
8:46pm 79%
9:34pm 95%
9:47pm 97%
10:13pm 100%
Any idea why it would have flipped from charge to discharge?

If you don't have a SIM card, I recommend putting your phone in airplane mode to keep the cell radio off. You can turn WiFi on after enabling airplane mode.
I was just about going to create a thread about it. My battery takes a full night to fully charge even with the phone turned off. What can I do so I can improve it? It is pissing me off seriously.
