Non-HTC batteries can disable GPS?

According to a review on pdashop.nl, their 3rd party battery makes the GPS not work because, according to HTC, it lacks a metal cross that is supposedly part of the GPS antenna?...
Anyone heard of this? I am looking at getting me a 2880mAh extended battery (with OEM cover) to improve the phone's useable battery life...

That's nonsense.. I have a mugen and still have good gps. Just buy your batt.

Hey landgenoot! (En Provider-genoot <G>)
Thx both for the reply... It sounded like b*ll***s to me too, but since I am new to the Vario III (TYTN II/Tilt/Kaiser), I wanted to check...

I worried about getting backup batteries that don't have that cross, but I got a 1600 mAh standard size, and GPS works fine.
I still have not seen any explanation of the purpose of the metal cross on the OEM battery - does anyone know?

I imagine it assists with heat dissipation.

I still believe that it's an R/F shield, probably to pass some stray emission spec.

I have various backup batteries and GPS also works perfectly fine. I concur with the screen + ariel explanation, in that it "may" enhance the gps (perhaps?) about .00000001%. Like wearing socks on your feet helps protect you in a thunderstorm (LMAO)

Epic vs Evo battery differences

Epic vs Evo battery differences
Something I noticed while having an Epic and Evo under one roof was that although they both last about the same length on a charge, the components using the juice vary greatly. Here’s is a breakdown of the most power hungry items arranged from most power usage to least:
Evo:
• Cell Standby (most power usage)
• Phone Idle
• WI-FI
• Android System
• Display
Epic:
• Display (most power usage)
• Cell standby
• Phone idle
• Android System
Initially I thought that the Epic’s AMOLED screen was WAY more power hungry than HTC’s LCD. But if that was the case I would expect the Evo to outlast the Epic on a charge which wasn't happening. Then it hit me. Samsung’s Hummingbird CPU/GPU is 45mn and is supposedly eating less power than the older 60mn Snapdragon processors. If true this could explain the reversal of the “Display” from being at the bottom to being at the top. I suspect the AMOLED does require more juice than HTC’s LCD but perhaps not as much more as I originally thought. What is likely going on is that the system components are less power hungry on the Epic but the screen is somewhat more power hungry. This could explain why Evo’s and their custom undervolted kernels see a big improvement in battery life, simply because the underlying cpu/gpu is using a larger percentage of the battery’s life.
The other noteworthy item, Wi-Fi was always in the middle of the list on the Evo but doesn’t even show up on the Epic even though Wi-Fi is always enabled. I have heard the Epic uses a newer low power Wi-Fi chip and if that’s the case it seems to have paid off.
My Conclusions:
1. If you want more battery life on the Epic, turn off auto brightness and set the brightness quite low. Set applications to “dark” theme’s when available because black pixels draw no power on the amoled screen.
2. If you want more battery life on the Evo, you’ll want to look into rooting & custom undervolting kernels (and you’re in the wrong forum…haha).
I welcome your comments and to know if you draw different conclusions. Thanks!

Well I've heard the samoled takes less power than the lcd but idk. Just putting some info down.

1. If you want more battery life on the EPIC, get a custom ROM (viperrom) running 2.2. Helped me get from 8-10h with low use to 16+h with moderate/heavy use.

Yeah stock epic battery is horrible.
However, on dk28 its much much better battery life
Anyone else notice that the screen always takes up about 90% of the power? Lol but that doesn't mean it won't last long
I just made a thread about how I watched two full length movies on the highest brightness and I'm at 13hrs right now still kickin lol

I have said both of this things on other threads today, but they bear repeating here.
First of all, SAMOLED uses more power than LCD in most cases. It uses less power than regular AMOLED. If you go back and read Samsung's press releases, they say that fact. They don't claim better battery life than LCD, and you know they would be the first to say it if it were true.

The Galaxy S devices have software issues that cause some of them to use their antennas constantly. With this issue, the battery drains in 10 hours, at best. You should be getting at least 20 hours out of your battery with moderate use. If you are experiencing these issues, chances are it will happen on all ROMs (as it did with me). I know two other people who have Galaxy S devices and they both have this issue. Mine started getting 20 to 30 hours when I switch to DK28 (and my GPS broke, not to mention occasional FCs and a broken WiFi tether), so I am betting this will get fixed with the 2.2 update. The above quote further supports this theory.
BTW, the whole "recalibrating the battery" thing does not help and can be harmful to your battery. While I am dispelling myths, clearing a cache or resetting a partition more than once is a waste of time. If you ever hear someone say "clear system 3x", they are just being superstitious. Maybe they have accidentally hit "no" instead of "yes" when they cleared it in the past, and ever since then they decided to do it 3 times.
One more myth! Most benchmarking tools for Android are crap. Quadrant has been shown to give highly inaccurate and easily manipulated scores. I used to think Linpack was good, but I have heard of G2's getting like 33 MFlops, which is ridiculous and makes me think it is bad as well. Any benchmark that takes into account FPS is only accurate if you remove the FPS limiter on your phone. All phones that I know of are locked to a max of 55-60 FPS (Epic 4G is locked to 55.6). What that means, is if you put a 5ghz quad core CPU with a GTX 580 in your phone, you would still get 55.6 FPS with those benchmarks (such as Neocore).
BenchmarkPi seems to be pretty accurate for CPU. An3DBench seems to be OK for OpenGL and 3D benchmarks since they tend to tax the GPU so much that it doesnt ever hit its limiter.

quite impressive camera but battery life...

Well.. last month I planned a trip to visit my sister. I’ve heard a lot about EVO camera and I just had one borrowed from my friend, though i already have another model of HTC…anyway I thought this might be a perfect time to do a small review of the Evo.
Below is my experience with her Evo 4G.Before that, I want to stress that my focus was to have fun and not make this as an in-depth review of the phone, and i also not compare it to my HTC.
First the Sprint's maps told that on our area but it has almost complete 4G coverage. The tests from different part of the vicinity only shows mostly 3G connectivity. And if it does show 4G, I don't notice any obvious change in speed.
I prefer Google Navigation which I think is excellent then Sprint's because of the satellite viewing while navigating... even better than the capability of full-fledged navigation devices…There were a few times that google navigation would give a longer/slower route, but so does all other GPS devices. Over all, I'm pretty impressed with Google Navigation.
I have to admit that this camera is a lot impressive to me. It won't replace a regular point and shoot camera. But this camera is excellent for internet viewing. Reduce the size to 25% of it's original size and almost all it's image quality issues will be greatly reduced.
About Battery life... The battery didn't last long for me, and surely I did put brightness to auto-brightness, turned off 4G, GPS and wifi When I wasn't using them. It barely lasted only about 3.5 hours, good thing I got my 5200 mAh extended power bank and an replacement battery. I didn't notice any major difference between the OEM battery and the replacement battery.
Again notice that my focus is to have fun and try my new phone camera. My battery after second charge held out till we got back home, with me posting on FB. Overall, I have not too much to complain about, I just found some solutions to my issues. The only solution I haven't found yet, is the 4G coverage. From Sprint's map, it says we're fully covered, but as I go from place to place, the 4G coverage was spotty at best.

S6 Broadcom Chip

"This special localization chip enables the Galaxy S6 to collect and compute data from Wi-Fi, Bluetooth and GPS modules on one single chip which results into far less battery drain."
"The Galaxy S6 indeed touts Broadcom BCM4773 and estimates that compared to existing solutions this chip provides power efficiency of up to 80 percent. This will go a long way in ensuring that the 2550mAh battery in Samsung’s latest smartphone can last even longer."
Great news!

Surely
Samsung has long experience and history of great battery life and off course they know what they are doing..

Was the S4 known for its battery life? I didn't experience good performance on mine. I got nervous every time it went below 50%.

Listening chip?

Will the 6P have that dedicated chip that's always listening for the OK google hotword without heavy battery drain?

The question is "without heavy battery drain"
Moto said their service was on a low draw core on the Pure and they were full of crap because turning off all their crapware is the only way you can even net anything close to decent battery life. Can google get it right? I don't know but I'll probably turn it off regardless.

Isn't that part of the Android Sensor Hub?

I wonder if the Android Sensor Hub is just a fancy name for the Hexagon DSP in Snapdragon chips? I've been using the always-on function of "OK Google" on my Note 4 for quite some time and haven't noticed any significant battery drain. I've left my phone off the charger overnight and I typically get about .5-1% drain per hour, depending on what notifications I get during the course of the night. That's about what I had before turning on "OK Google". The only issue I've had is the consistency with Google Now activating with the screen off. I think Android sometimes kills Google Now if it's not used in a while.

Using ok google everywhere in nexus 6 all the time.. Works great with screen off... Love this feature... So useful when u dont want to pick up the phone or driving.

I can't bring myself to talk to my phone..... I've tried and felt like a complete pillock!

I hope this function works on the 6P still and doesn't drain a lot of battery. I do use it a lot with my N6 right now. However, I only use it when I am alone I could not think of talking to my phone like that in public haha.

Huh? It's a sensor built into Qualcomm sd chips. The nexus 5 had it. It just didn't have the software for always listening with the screen off..... I think it was on the nexus 6 because it was a moto and Google owned moto. Id assume we wouldn't go backwards. Since the functionality is built into Google's own app. I think it's safe to say it's here to stay

No this is supposed to be a different sensor not the DSP you are referring to. The Android Sensor Hub does more than just always listening, it allows for more accurate step counting, finger print unlock without waking the phone etc... Watch the keynote for the launch of you want more details
