Battery drain with Navigation software [solved]

Hello everyone,
I've noticed a strange issue:
I've connected my device to my car charger and I've used Copilot 8 two times: one this morning going to work (25 minutes of trip) and another going home this evening (25 minutes again)
I've found that even if the device is connected to the charger, after 25 minutes of usage of Copilot, I've noticed a 4% of battery comsumption!!!
I've retried again this evening and I've noticed this again!
I remember perfectly that with other HTC Devices (Kayser and HD2), I've charged and used the device without battery consumption.
There is someone that noticed the same things?
Any suggestion, please?
I think it's not acceptable to have my Desire discarging during a (long) trip!

Sounds to me like your car charger isn't putting out enough power to keep the device charging whilst in use.

Yes, I hope this is the matter.
I've ordered another original HTC charger. I'll update this thread as soon as I receive it.
I'll try to enable GPS and make a simulated trip using the home charger.

Yep, seems the probable cause. I used to have same issue on another device used with a cheap low (500mAh) power on it.

The charger I'm using is original HTC charger for my old HD2.
I'll try with the new one.
Thanks to all of you for your help!

yeah i think ronnyuk already explained it couple weeks ago, strange but seems to be true unfortunately

I've had the same problem. I cant be bothered to find my own thread where I explained it, but if feel free to do so.

I had the same with my Xperia X1 using TomTom. I was using a cheap no-brand car charger from Maplin.
When I bought an official Sony Ericsson one, the speed of charging improved drastically.
As an aside, the cheap no-brand charger eventually ended up killing my mp3 player and making my phone stop working until I removed the battery for over 4 hours.

In 8 days from Expansys I'll receive the charger for my device. I hope to solve the issue.

As I wrote in another forum, another user had such an issue with an Acer Liquid, while I didn't using a commercial car charger I bought months ago for my iPhone (it's a "LoveMyPod brand, with two USB ports).
Didn't try it with Desire yet, but as Floating said, I suppose it's a matter of howe much power the charger is providing

Just goes to show that you really DO get what you pay for with cheap accessories.
Sure you might save a bit of money at first, but you're also risking harming your device in the process.

Too true. And of course, this happened whilst I was on an epic road trip of Europe, with the whole trip itinerary on the phone and ONLY on the phone!!
A lesson learnt (especially as the official SE charger in Italy cost me the equivalent of £30). Thankfully the mp3 player was just a cheapo thing but still, very annoying

Hello everybody.
Yesterday I've received the charger. This morning I've tried it and it works!!!
Thanks to all.

isn't the charger for the HD2 that you had original (CC C200 ) the same as the desire ???

Yes they are...

Not for me. With HD2 I've received an HTC Charger with MiniUSB->MicroUSB adapter.
If I use this charger, I can't charge my Desire using the Navigation app.
With the charger I've received yesterday, I've charged the device during the usage of the nav app.

[REQ] We need a Fast Charge Battery Driver

Like most of the others in this section, I come from the WinMo world. I just got my OTA'd Evo and I have to say, the battery takes forever to charge. My Touch Pro2 & Touch Pro both have no2chem's fast charge battery driver(it makes it feel like they fully charge in 5 mins) and since we haven't seen him in a while I thought someone else might be able to develop one for our amazing Evo's!!
Please Help!! Thanks in advance!!

Can you provide more info on this? A full charge in 5 minutes sounds ridiculous but I won't out anything past XDA

Sent from my PC36100 using XDA App

this has been spoken of before on these forums... it might be in the works, but you are reffering to a fast charge via USB connection rather than wall connection. Wall connection is full speed, USB is throttled down to prevent damage to the USB port on the computer plugged in to.
the process is a great add if you use tether charge a lot, like I do. If I am constantly streaming online on my old winmo phone even with fast charge I would slowly deplete my battery while it was plugged in, I haven't used the EVO much for streaming but I would be afraid to see the results w/o fastcharge.

thats why you buy a couple extra batteries and a wall charger

This. Got a replacement battery and charger on ebay for under $10 shipped. Works out great. Just swap the generic out with the stock whenever my battery starts running low. The only time I ever plug in my phone to charge is at night.

Seriously - if somebody is requesting a valuable piece of development in a development forum, what value are you adding trying to sell him batteries!? Do you honestly think he's gonna be like, "Oh hey, yeah, you're right! Who needs a phone to charge fast when I can just carry around a pocket full of spare batteries and a charger! Why didn't I think of that?"

Perhaps he didn't realize how inexpensively good-quality replacement batteries and chargers can be acquired. Also, a single battery inside a charger case isn't much larger than a wall charger + cable (which by your own assumption he must be carrying around in his pocket).
I understand what you're saying about it being a developer forum and all, but I don't see any harm in offering a feasible solution to a posed problem. I mean, look at Apple. They told people they had to buy a case or stop holding a phone with their left hands!

+1 for this

5 Minutes to charge and 10 minutes of use sounds about right for WiMo

I wish when connect to USB it would trickle charge. that way you don't the drop as soon as you disconnect the phone. so i guess i want to slow things down a bit but just when on USB.

This!

Yes, we need this for sure! Carrying around batteries is NOT the answer.

it wouldn't really charge in 5 minutes, but it would charge about as fast as plugging it into the wall.

this fast charge thing is NOT new to most of us that frequent XDA and other dev/mod forums (PPCGeeks)...and it is perfectly legit to put out a request for...
suggesting an extra battery is good and all...but not always feasible. Apple suggesting what they did was to redirect everyone's attention to THEIR lack of attention on a piece of supposedly high end hardware..that now seems to be flawed. OP has been around for sometime...and the extra battery thing is a good idea already...especially for noobs

Panasonic QE-TM101

Unless I've missed it from my research but I haven't seen any mention of this Wireless Qi charger from Panasonic. Seems pretty good as it also goes and detects the device, so no need to move the phone or the tablet around to ensure it is charging. One fairly common complaint I notice is that they have to move the device around to ensure the charger finds the phone\tablet.
I'm wondering if anyone has any experience with this as I may be picking it up for my Sexy Nexie 4 and 7. Or at the very least, here's another option for everyone to look into for their devices.
Here's a video review of some drunk guy on YouTube.
http://www.youtube.com/watch?v=EUpr6JkP5ow

I have had mine for a couple of weeks. Love it. My tablet pretty much stays charged all the time.

I have one I bought for my Nexus 4 as soon as my N4 arrived in January. Works fine with the Nexus 7 - although never seems to switch off from charging. When I leave it charging over night the charge light almost always on in the morning but the Nexus 7 only feels barely warm. So probably it is just trickle charging.

From your experience approximately how long does it take to charge the Nexus 7? My other concern about wireless charging is how it affects the battery life overall. I'm assuming you guys only place it on the charger from empty to full all the time?

x2, I am afraid it would shorten the battery life.

Pretty much I am either holding my nexus or it is laying on the charger. From its lowest point, maybe 20%, it will charge to full in 4-5 hours. Then the light on the charging pad starts flashing.

I should add, the nexus is noticeably warm when I take it off the charging pass. This is not a trickle charge.
Sent from my Nexus 7 using xda app-developers app

To clarify my earlier post:
Charging for N7 takes a long time - I guesstimate charging time is 5 or 6 hours. I normally charge it overnight. My N4 charges and switches off at around 95%. N7 charges to full charge.
The Panasonic charging coil seeks out the best position for charging the device. The N7 coil is physically in the centre of the back, so position placement really doesn't matter much.

flashing means something wrong

I have one, works perfectly well with the Nexus 7. The charging coil in the station is motorized, so it'll sound like a quiet inkjet printer when it positions the coil, but it's not loud at all and doesn't bother me. Works especially well if it's on your nightstand... especially when it's time to go to bed and you're too tired to bother with a cable or another Qi charger in the dark. As long as you don't place the tablet like halfway off the station, it should work.
As far as cutting off charge, some people have said that it charges to 100% then won't initiate charging again until the device drops to 90%. Haven't really had a chance to test it, but every time I've picked up my tablet after a night of charging, my Nexus is at 100%.

totally not trying to thread-crap.... just figured I should mention that AT&T is selling the Nokia DT900 at half price.. $25 for wireless charging is great way to give it a try. It's working perfectly with my N7 and N4... I just ordered a 2nd.

Thanks I've seen the thread and it is a very good deal

Have had this since my nex 4 this came out a year or two ago, I saw it there when I was in japan.
worked fine on my nex4 and nexus 7 2nd gen.
I tried it with the yijieneng receiver on my s4 but didnt work with case on, didn't try it without.
been using the samsung pad because it tops off the battery, where as the panasonic stops once it hits 100%.

I ordered one friday, and it arrived today (tuesday) from eBay second hand for about $25
Using a generic QI receiver from ebay, when i first turned it on and put my phone on, 'oh hello phone here have some power'
then my curiosity attacked me and said 'THERES A BUTTON THERE PRESS THAT BUTTON WHATS IT DO!? so i pressed it then got to spend some time trying to figure out what i had done. DONT PRESS THE BUTTON, i think it has different modes, for finding the phone, after i pressed it the pad wasn't happy with my phones location and just kept moving left and right not charging.. but its working now xD
Im trying to find a copy of the manual online but not having any luck...
Haven't tested the speed yet, but its rated at 1amp so i presume it to be the same as most QI chargers on the market
Edit: speed is great.

Odd. I, too, had purchased a Nokia DT900, and it did not work with the Nexus 7 for me - AT ALL! I have since read that it didn't work for many Nexus owners.
I had to return it.
I then bought this Panasonic model, and it's been flawless (even through my MOKO case).

Sorry to hear it. The DT900 was a total bust with my N4, but still working great with my N7.
Sigh, as others have said, it still feels like this is such a beta level feature (ie. that there has to be so much luck getting the right combination of products to make it work)

Still waiting for mine that was ordered from eBay. Once I saw the tracking feature with the LEDs it was an instant buy, lol.

[Q] why was this device discontinued?

hi all,
somewhere it was mentioned that this device was actually ignored and not discontinued by sony due to the issues related to the hardware or something. I just recently purchased this and im actually worried bout this. was my decision to buy this particular handset a wrong one?

no its not like that..its's still available here in my region....

Not really.. it has the same hardware as xperia Z.
Except for infrared blaster.. which, yes had a hardware issue (which can be exchanged if you bring it back).
If i was discontinued in your country, it's because Sony put all marketing towards Xperia Z, not ZL... which I understand because it had something the competitors didn't have: waterproof.
I still hope they will make a ZL2 though, waterproof .

Its discontinued because its old and past its life cycle. Same with the Z. Just because carriers have the phones, doesn't mean Sony is still making them. But If you by one brand new, even if its a year old, you will still get full factory warranty, so don't worry. But most android flagship devices have roughly a 3 - 5 month production life. Then its on to designing the next one while the older models slowly sell out. Only a handful sell enough units to keep production going, like Samsung galaxy "S" flagships, and possibly even the HTC one. Although with the financial state of HTC, I don't think the one was enough to pull them out if the fire.
But I wouldn't worry about your purchase. This type of tech gets "old" within 3 months of release. I mean the zl came out with the snapdragon s4 pro, then a month the later we had the HTC one and S4, with the snapdragon 600. Then we got the Z ultra with the snapdragon 800. Now that thing is old news. Lol. Technology drives me nuts!
Sent from my C6503 using Tapatalk

It's all about marketing as wrote ATRIXXIRTA, Sony makes money selling new devices...in certain way forcing people to buy new models.
Anyway I am happy with this device.
They put a 5 inch full HD display on a compact chasis, with infrared controller (works fine for me), great hardware inside, support for external memory and with FM Radio
Remember iphone arguments about size? It cannot be bigger because of one hand use? Or samsung explaining why they removed fm radio from galaxy S4?
They said too that external memory cards are becoming obsolete because of cloud storage? Come on, just marketing dudes

Its true. The ZL is one of the BEST all arounder's out there. If the Z or Z1/2 was the same size as the ZL, it would be the design to beat. Or the moto x if it had an SD card slot, lol
Sent from my C6503 using Tapatalk

There are aspects of the screen on the ZL that could be better...
Overall it's a really nice phone and I'm fairly happy with battery life, and performance.

Bad experience
I had just bought the phone in the beginning of feb and had a good time, enjoyed my phone. Unfortunately, the battery started giving a problem on 10 of this month, phone only starts through charger, once charger is plugged out, the phone switches off. Gave it to the customer care at Mumbai, India & they said my phone would be replaced. After 10days they got me phone that was used and scratched, it also had glue at back of the cover.
Just having a bad experience as my phone was brand new & now they are giving me a **** of my money. Bad customer service from Sony.

That's total bull**** man. Make a video and post on YouTube and spread it as much as possible. Might not seem like much, but if it gains enough momentum, Sony will take notice. Mine Is also starting to give me issues. It will shut off randomly if it gets warm, and it will only boot plugged it. Today for example, I was using navigation for about half an hour, and it just shut off randomly. And I couldn't power it on until I plugged in the car charger. I can.unplug and use it however if it cools enough. It's fu#ked and I'm passed! I'm thinking of ordering a replacement battery. 22-25$. I'd rather have it.BEFORE this one craps out, and not wait until it actually goes, then wait 2 weeks for a battery!

3rd Party Chargers (also, beware of faulty ASUS chargers)

I'm curious if anyone's found any 3rd party chargers (or cradles) yet. Mine overheated and had a meltdown and I'm having some difficulty getting Asus to replace the darn thing.

I tried for 2 weeks to get them to help me and both tech & customer service were pretty inept. By the time I'd gotten to the point where they were willing to replace the cradle, I decided to just return the thing to Best Buy.
Were I to do this entire thing all over again, I'd have just gone to Best Buy for an exchange. They do it immediately, no questions asked. Asus is hopeless.
But to be honest, I was sorta glad to give it back, charging issues aside. The watch just didn't do enough for me. I liked it while I kept my expectations low and tried not to think about it. But when I did, boy I'd get a bit frustrated with how half-baked it was, even as an early adopter product.

Weird, I feel almost exactly the opposite, that there's very little about it that needs improvement. I guess I'm coming from a different place. I was really an early adopter: I used the first Sony Smartwatch for 2-1/2 years before getting the Asus. Compared to the old Sony, these Wear devices are amazingly good.

Same here. Love mine for now. lol

Could be the problem root cause be that the charger shipped with the cradle has an 1.35 A output , while the cradle itself is badged Input 5V, 0.5A ??? little bit too much current!!!
rdgs
H.

I actually had really good customer service from Asus. I emailed them, got an RMA and sent the watch and charging cradle to them and had it back within a week. They replaced the battery in my watch and gave me a new cradle. I sent the watch too bc I couldn't even power it on. I have pretty happy with it and have had it since Christmas.
Sent from my Droid Turbo 64GB BN

I charge watch from PC with USB 2.0 with max current is less than 1A (my guess it is limited to 0.5A) so hopefully it won't overheat. Still enough to fully charge watch in a reasonable time.

No. As long as the voltages match, you should be good. The current needs to be the same or greater than what the watch expects. It will pull what it needs. What would be bad would be an adapter that is greater than 5V. I fried an old Palm PDA that way back in the day when I was getting started. I'd be curious to know if the watch was doing anything intensive when it was charging (something that would keep it on an generate heat and warming the charging paddle up) or if it was placed somewhere that would cause it to heat up?

Hi,
I'm using the usb cable connected to my laptop USB, it takes a long time to charge (sometimes it's seems like it's not charging).
And i also have flickering screen when browsing through the quick settings.
can anyone tell me where i can get a EU charger? i've ordered mine in the US , but i live in europe.
Or maybe i just can use a generic US to EU adapter for the wall charger?
Thanks!

It doesn't work that way. The current rating denotes the max current the watch would ever draw, and the max current capable of being produced by the converter.
The converter can output a maximum of 1350 milliamps, whereas the watch consumes 500 milliamps. There's no way the watch would (under normal circumstances) consume more than 500ma, unless there's a short circuit. I suspect the problem was a thermal issue in the internal lithium-ion battery. If the charge regulator doesn't detect that the battery is fully charged, it won't shut off the input current, and the battery can (eventually) go into thermal breakdown. See Thermal Runaway.
