I was just wondering what the correct way to charge your phone is. I have an AT&T tilt. When the battery would get to like 3% I would just turn it off and then plug in my AC wall charger that came with it and leave it until it was fully charged. But I want to leave my phone on all the time so I dont miss calls, So when I leave it on while charging the phone gets pretty warm and the screen turns on by itself randomly. And when i plugged it in the other night before i went to bed (phone was still on whole night) in the morning I went to wake it up and it wouldnt. When i slid the keyboard out it lit up and everything so it was definitely on, but the screen wouldnt come on no matter what I did. Am i not suppose to be charging it while the phone is still on or leaving it plugged in for a long time after the battery has reached its full charge using the AC wall charger that came with it. Should I instead by one of those cradle chargers cuz dont they have a thing where once your battery is full, it will stop charging it? Any feedback would be really appreciated. Thank you.
hmm i dont really know bout u
but i've really never turned off my phone....the tytnII or any of my previous phones i would just leave it on day and nite and i go to bed i charge it or any time when i'm home if its low on battery
kinda wild how many people torture their batts on acount of that old myth

How are you charging it? Supplied wall charger or USB port?
The supplied wall charger will turn it on initially and it should then turn back to standby as set by your power settings. Make sure you don't have it set to ramain on when on external power.
USB charge connection to PC or laptop will keep polling the phone if Activesync is enabled and turn it on continuosly.
Some external chargers, such as the ones for the previous TyTyn (not TyTynII) required two pins connected to enable charging and if you are using one of those the TyTynII thinks a data connection is being made and randomly powers up.
It's been my experience to keep the battery on a charger whenever possible. Those batteries "like" to be topped off. I have killed a couple of batteries by running them down all the way and trying to bring them back to life. Li Ion batteries are not like NiCads
When I'm driving, it's plugged in. At home, it's on my desk charging. While I sleep, it's charging on my night stand.
I found charging when every possible, and keeping it topped off as much as possible will enable the battery to last longer for those times you can't get to a charger. This has been the case for all the HTC phones I've used.
Without knowing what it was, I encountered the RLOD on my phone after leaving it on USB overnight. After reading the first two or three pages of two different threads I tried the little lucky "fixes" and found that none of them worked.
I have a backup phone and need my phone for work, so I put my SIM in that phone only to find it was dead. Went to my local AT&T store and they said the SIM is fried. They replaced the SIM and everything is working now.
I replaced the battery in my TyTN and now I'm recharging my original battery. The phone works without problems, or heating up, or shortened battery life.
So here is my theory:
The phone has a similar monitor as the offgrid solar system does. It's job is two-fold: don't let the battery overcharge -and- don't let the battery every discharge to 0.
I suspect that most problems may happen when the phone is connected to a laptop or desktop computer via the USB port and left on when the computer goes to sleep. At this point, the scenario is similar to a monitor on an offgrid solar home. The monitor decides when to pull from the batteries and when to fire up a generator. But if the monitor is set incorrectly, it constantly flicks between charge/generator and the end result is a huge draw on the batteries (rather than a charge going into the battery).
Now with the laptop asleep the trickle charge is way lower than normal. Activity on the phone may also actually flick the laptop in and out of sleep mode. The basic end result is the phone starts the same type of draw between battery and trickle charge, causing a higher than normal draw on batteries, and finally it heats up the chip on the SIM and fries it either partially or completely.
If you have "resuscitated" your phone, but still have problems, simply replacing the SIM should fix it. If you get the RLOD I'd say get the SIM replaced as it is fried. Once you get the SIM and any SDHC card out, very tentatively try to recharge the old battery on the wall charger. (In other words, don't take your hand off the charger when you plug it into the wall) If you get a yellow light, breath easy. If you get the red light, UNPLUG IMMEDIATELY and throw that battery away!
My research on offgrid solar has been going on for almost a year and I began this theory when I noticed a few things:
1) I saw posts from people with not just HTC phones getting a red light.
2) I saw a few posts where people mentioned they used the USB overnight.
3) I have seen firsthand what the constant toggling can do to a 24V 1500 kilowatt hour battery system and the heat it generates.
Except...
There is no USB power when a laptop is shut down except for a few newer models which are designed intentionally to do so. And USB activity does not wake the laptop, particularly not "in and out" of sleep mode. If it does, your laptop has problems.
Final point.. Hasn't it been ground in to use the supplied charger? Most people who report failures admit they were using third-party chargers.
That said, a USB cable should be a more reliable charge source than a cheap AC charger due to the fact that a laptop has to have clean power itself and cheap AC chargers can fail in many fashions and often result in excessive DC voltage or AC voltage winding up in the source.
After testing last night and the night before. I have the result. 1st night I had the DS7 turned off, morning I woke up, was fully charged. Last night I left the device on. Woke up overnight still wasnt charged up. Now this doesnt seem promising for USB charging..
I know from G1 the AC charge always lasted longer then USB charge. Since USB can only charge to a maximum voltage. Guess the DS7 on 4g mode just uses more then it can charge. Kinda crappy. =/
I agree with that. I think it can be solved with a custom ROM using an optimized Kernel. That's what happened to the HTC G2, with the custom Kernel, it runs smoothly and battery last as hell.
Can you underclock with the stock kernel using something like SetCPU? Maybe with the screen off and set to a minimum clock speed it would do better.
SetCPU does indeed work. But I think it already lowers the CPU on its own when the screen is off. I think it has more to do with the 4g radio battery drain then it does the CPU.
The Streak 7 does not trickle charge via USB. It must be plugged in to charge.

Well I can confirm that too. Came to report that it wont matter about radio or cpu speed. USB doesnt charge the battery but it DOES power the device. So USB tethering will keep the device on and tethered and not drain the battery, it just wont charge it.
HOWEVER it WILL charge the battery IF the device is turned off via usb.
This is very common with tablet devices these days. Many Android tablets as well as the iPad do this. A USB "Y" cable connected to 2 USB ports simultaneously works though. Otherwise there simply aren't enough amps going to the unit. Newer USB ports that provide more than the 5V / 1 AMP current output also don't have this issue.
Ok update on something:
While Device is off, It charges to full. Plain and simple.
While device is on and usb tethering only to your PC. No battery drain, no charging. (Which is GOOD!)
While device is on and you are playing a game like gun bros or something more intensive while 4g radio is on or so, battery will drain.
So it does seem that if you do alot while on USB you will still get a drain, just not as fast. But since it doesnt charge it at all. Losing even 1% at a time.. is =/
Hi,
I have a new and flawless Note, the USB connector is OK.
At night I connect the Note to the charger and I put some music on to fall asleep. Playback is configured to just play one album once.
Normally I put the phone in Flight Mode, in order to sleep without unnecessary radiation next to me.
On some few occations (it happend to me for like 5 times now), in the morning, the phone is not charged at all! But I am 100% sure that the battery status icon on the top bar signaled the charging mode.
This morning it happend again and I noticed that I left the Flight Mode off (because my wife is away and I want to stay in contact if needed).
Also, I noticed that I have been using a ZTE charger specked with 750mA, while the original Samsung Galaxy Note charger is rated 1000mA.
Can it be, that I was using the ZTE charger on its limit and that having apps running, or maintaining flight mode off, was enough to actually not being able to deliver that extra juice to charge the battery?
The other reason could perhaps be a software problem, like some app draining the battery as much as the charger is able to charge, so in the end the battery stays more or less the same.
I am positive that the USB port is not broken. I.E. I tested by unplugging and plugging the charger from the wall socket instead from the phone and all is recognized OK. Also, no issues when connecting to the PC.
What is odd: on previous occations I think I remember that I just plugged the phone back and it charged.
I swapped the chargers, but still I have this odd impression, fearing that the device might have an issue.
Anyone had similar problems?
Cheers,
vma
Yes, looks like a weak USB charge problem. You get similar behaviour if you try to charge the device from a PC - sometimes I have mine plugged in to my PC at work all day and it barely charges. Get home, put the official charger from Samsung in from a walk socket and it charges in an hour or two max.

I have noticed that when the N6 is on charge, once it reaches 100% and left on charger, the battery starts discharging approx 1% every hour.
I only noticed this when my alarm was going off and when looked at battery usage it was saying 94% but nothing using it - installed GSAM and noticed that once fully charged it starts discharging even while on charge. If I remove charger and re-insert it starts charging again as normal.
Has anyone else noticed this issue. I have contacted Motorola to see what they say, but they are none the wiser and just think it may be a feature of the device/charger but not sure and said to test with another charger.

Not sure, I don't use stock or the stock charger. I would have thought the stock charger trickle charged. I remember my HTC desire used to charge to 100%, discharge to 90 and then charge to 100% in a loop as it didn't trickle charge.
Make sure your using a cable that supports data as well. My stock 5.01 and stock charger/cable does trickle charge.
It's perfectly normal to see this in such devices, though if it were going any lower I'd investigate further.
Maintaining a constant flow to the battery would burn it out so the charge gets it to full and then cuts out, allowing a little discharging and cooling of the battery. Once it gets to certain point, it'll start to juice the battery again.

thanks for the replies - I've not seen it drop below 90%, but I know if remove the charger and plug back in, it will start charging as normal - another thing I have recently noticed is that when you do plug charger in, initially it switches between battery/charger a few times and then starts properly charging - I wonder if this is feature of the phone or lollipop causing this. - other than this phone seems to work fine and have had over 2 days on a full charge
Well got it to drop to 80% while plugged in and it didn't start charging again until pulled cable and put back in
what charger are you using? i leave my n6 on a charger for hours after it hits 100%, and it never ever drops. id even say that when it hits 100% it doesnt stop charging. it keeps charging, with a much less inflow of charge than normal, but its still charging. for about 30min before it stops charging. then it just stays at 100%. sometimes i have it plugged in for 8-10 hours after, never once did it go to 99%. this is while using stock, and custom roms.

The new gen chargers actually cut the power when the battery Actually hits 99% and show it as 100% and stop it charging. But when the 100% drop to 99% (which is not actually visible), it automatically starts charging. But discharging the battery more than 1% is not actually a Normal thing, I should say. I also do charge over-night, never evidenced such thing. I'll suggest you to try with different turbo charger if you have one.
I'm using the stock charger got with the phone. I did contact Motorola over this and they were useless. I know charger works as charges to 100%. But it then just stops.
I have performed a factory reset to see how it goes tonight.
If still no good will speak with CPW and see what they say as don't fancy having to send off based on some of the forum posts
I have no issues with my N4 which has been connected to a power source for days and still shows 100%
I have also noticed that on the N6 when powered off and charge it doesn't show that it is charging
taken it into CPW and they have sent it off for repair - been told 16 days - at least with apple it's near enough same day, shame can't do same with android phones
I had called Motorola uk support and was promised email confirmation of call and also call back this morning regarding the phone and have had neither
back to my Nexus 4 for time being, just hope my Nexus 6 don't come back with any scratches, etc
I use a Qi charger, and notice this exact thing. Charge until it claims to be full, then stop altogether. So I set it on the pad when I go to bed, and wake up to it not charging and being down to around 95%. I was thinking that it was a characteristic of Qi, but when we got another (identical) Qi pad for the wife's Hammerhead, it "appears" to remain in charging mode indefinitely. Our Qi pads have a blinking white light when they are "charging".
what happens if you just plug the charger directly to the phone so not using the wireless Qi charger, do you get the same fault

Hammerhead does act differently to the shamu. I have both and used them both on the same qi.
Hammerhead trickle charges. Charging icon remains until picked up off charger.
Shamu stops at 100%, charging icon disappears. However, when I remove my Shamu, its always 100% or 99%.. Its never lower.

Good question. But judging by the rest of this thread, I suspect that it will behave the same with a wire as with the Qi. I don't ever actually use the wire to charge, since the ballistic maxx case makes access to the USB plug inconvenient.

I wonder if that could be a coincidence....? I.e., either you aren't leaving it on long enough for the percent to drop lower than that, or leaving it on long enough that it initiates a top-up just before you disconnect it.
Ok, so looking at the DT for the device....
https://android.googlesource.com/ke...ot/dts/apq8084-shamu/apq8084-moto-common.dtsi
Look at lines ranging from 823 to 854 for the smb1357 block.
Note low-voltage-uv = 2750000, max-voltage-uv = 4350000
In mv, that would be 2750 and 4350 respectively. That makes for a range of 1600 mV.
The recharge-thresh-mv = 200
Assuming a *relatively* linear voltage/percentage curve, 200/1600 * 100 = 12.5%. It won't be quite that linear, but this is adequate to give a rough idea of the charge cycle breadth in percentage points.
recharge-thresh-mv accepts values of 50, 100, 200, or 300. The smaller the value is, the tighter the recharge threshold becomes. At 50, we would be looking at roughly 3%.
So my conclusion: working as intended.
There is another aspect that becomes involved when using Qi, which is the bq51021. This one has a parameter "resume-vbatt-mv" set to a value of 4270 mV. That is 80 mV below full, or roughly 5%. Judging by only the name of the parameter, it sounds like it sets a Qi charge cycle breadth of 5%, but I don't understand the relationship between the bq51021 and the smb1357. I suspect that the two have to agree for Qi charging to work.

I don't think so. I put it on the charger at pretty much the same time and take it off at pretty much the same time but starting from different % remaining every day... If it did drop to 90%, i would have caught it at least once by now.
update: whatever you do if you are uk customer and purchased via CPW do not take it back to them - i found out today that they are not accredited repairers and they should have advised me it needed to go to Motorola - now trying to find out what is happening with my phone and when to get it back
I'm still trying to understand how my Nexus 6 works with Qi charging, and the results are a bit inconsistent.
I'm using an LG WCD-100 stand and a BlackBerry Blade charger, both of which are reported to work well with the Nexus 6 (in portrait).
I've had my Nexus 6 on the dock on my desk in work this week, and have been keeping an eye on it. I have the screen on all the time (so I can keep an eye on incoming personal emails). Most of the time the N6 charges to 100%. It then stops charging until it get to about 98%, at which time it starts charging again. So far so good. HOWEVER, on a few occasions it did not start to recharge (even with the battery down to the 70's), and I had to remove it from the charger for a few moments and then put it back before it would start charging again.
I'll try again next week (I'm only desk-bound Tue/Wed/Thu) with a different Qi charger, just in case there's a problem with the one I'm using (though I doubt it).
In the meantime, has anybody seen similar behaviour - or is it time to talk to Motorola UK Support?
the charging issue with it not starting again is the same as what i'm having on wired connection - if you install something like gsam battery monitor you can see that it is discharging while actually charging
I also have the LG WCD-100 (from when I had the LG G3) but not actually using it as I think first time tried you have to get it in the correct area for it to charge
I had problems with my Nokia charger. Because this phone is big and the back of the Nokia was less than half way up the back of the phone, the weight of the too of the phone pushed the bottom of the phone away from the charger.. Imagine the phone as a see saw and the top of the back of the charger as the pivot point. Also the unflat back didn't help
