Charging speed - BLU R1 HD Real Life Review

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the BLU R1 HD can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Must use Blu charger. Otherwise, charging speed will be 30% lower. I checked with Ampere. Using Blu charger, can charge from 10-100 in about ~2 hours. Not bad.

My experience has been different. If you're heavily using the phone (google maps for navigation for example) the battery will barely charge and it will get very hot. The phone maintains charge well, however charging it up is definitely a 3-4 hour process, if I plug it in for 15 minutes with no use it's about 5-10% on the battery max. I did not find the charger that came with the phone to be any different than most other chargers I had lying around, same charge time (most were higher amperage anyway, being throttled by the phone regardless).

3 because it does charge very slowly, even compared to older non fast charge phones I've had, I think I read that it maxes out at [email protected] which is quite slow.
It's not as big of a deal as the battery life is excellent and it was only $60, but you can't get around calling the charging slow

Definitely limited charging speed, if I use a Samsung 2 amp charger im looking at about 3.5 hours to max charge, whats weird is I used a Samsung 1 amp charger and achieved full charge from 8% to full in just under 2 hours. How does a manufacturer cripple charging port?? -_-

Yes, that's why I said you have to use the Blu charger. I have no idea how they cripple it.

Here's how long it took to charge my R1 HD from 1% until 100% with the Wi-Fi on and radio on. 2 hours and 39 minutes...
Standard BLU charger and cable used.
It's really crappy that BLU somehow cripples the charging time if you choose to use a different charger or cable.
That's got to be the thing I hate the most about this phone. Sigh....

I just got his phone and while I work I stream videos and music all day long at my desk. I keep the phone plugged in the entire time and I've noticed the battery percentage will only increase 1% per hour while charging & using the phone at the same time. Previously I was using the iPhone 6s doing the same thing, it charged 100% quickly. But with nothing changing on the iPhone 7 I switched to android on a cheap phone while I wait for the Samsung Galaxy S8

How does the device behave with Power Banks or 2.1 V outputs?

Samsung Charger better than LG's

Hey everyone
Just want to ask if anybody noticed the same as me regarding the charger of LG:
if I plug the charger and use the phone it heats up really fast and charging speed is slow. The heat slows down my 4X HD and the performance is sh*tty as hell.
I once forgot my charger an used one from my dad's Samsung and I noticed a incredible difference. No heating at all and it charges much faster (with LG over night ~ 8 hours sometimes not even fully loaded from 15%, with Samsung 4-5 hours full with YouTube use and other minor things).
When I use my phone while plugged with LG charger it often even drains some battery (2-3% in 20 mins discharge, then charge up to 5% in the same time and so on).
Have anybody got the same "problems" or has my charger maybe a hardware failure?
Greetings

Weird. My phone charges from 0%-80% in like 1 hour, then the last 20% tend to take while longer. But also if I "Overcharge" it (that is to say charge it for about 2 hours when it's still 100%) it feels like it has charged 110%. Cause it takes forever to go down to 99% but then it decreases faster.
This is with the included LG charger. If I use my samsung (which is like 500mah) it takes longer.
I don't experince any performance decrease when charging.

Are you on stock rom or on a custom rom? I'm on WerewolfJB and that's maybe why it heats up but the faster charging with the Samsung charger is really noticeable, especially when I use the phone, like I said.
Thanks for sharing your experience with it

I'm on a AOSP rom (Slimbean). But I do share your experience with heat, both on the phone and the charger itself. But I think it's due to the high currency.
Your charger could just be broken. LG charger's output current is rated at 1.2A which means that the battery should be charged from 0% to 100% in about 1 h 45 min. It could take longer if the charging current gets smaller when the battery is starting to get full.

wrong, "charger" is not current source
for topic: your charger is bad, replace it
I had an issue that CPU was always 760mhz while charging with zen+HYPER governors. RevoltJB+OP kernel 2.53.
Noticed that my raspberry charger(2A) was faster than LG stock charger. Also normal for me too that battery even decreases while using phone at charger.

there is maximum allowed current to charge phone. it is controlled by electronics inside the phone. if you are using charger that has bigger maximum current it is possible that phone battery is faster charged, but as i said, it depends on interior charging circle
Charging Current 101
To clarify the above responses:
The LG charger *should* be more than adequate to charge the handset, as that is what it was designed to do....
If you were to use a different charger, e.g. one from another phone or a shop bought replacement, then the maximum output current of the charger is an important factor: the lower the rating (in mA or A) the slower the charge and therefore the longer it will take. Using the phone whilst charging will also increase the charge time as you are using the battery whilst charging it (like filling the bath with the plug out), more so with apps that load the graphics processor (GPU) such as youtube or games as these are battery intense tasks.
The rate at which the battery charges is ultimately decided by the handset; most modern phones will fast-charge most of the way, then slow charge the last few % to avoid overheating and damaging the battery, so having a charger rated to, say, 2.4A (or 2400mA) does not mean the battery will charge twice as fast as one rated at 1.2A as the phone dictates how much current it needs.
That will either clear up a lot of questions or will mean nothing at all

Same. Charging here is very fast overall.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the LG V20 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
I use Ampere to see the rate I am getting. First plug in might only be 90 mah. I unplug, replug, it jumps up to 350. A couple more times and I end up at 900-1200. Screen off and let it fast charge.
I recently tried out the HTC Bolt for a couple weeks and it seemed to charge much faster than my V20. Shouldn't it be the other way around since the Bolt uses quick charging 2.0 while the V20 uses Quick charging 3.0?
Slowest charging phone i ever owned but i still love it lol
My H910 charges relatively quickly. Just plugged it into a quickcharge 2.0, not 3.0 car charger and it went from 16% to 50% in ~25 minutes.
I regularly get rates of 1.8A or greater using a CHOETECH or Anker charger. One its above 80%, it drops down, but this is normal.
The Anker is QC3.0 and the CHOETECH are QC2.0

even my old G2 get 50% battery in half an hour.
what's with V20?
it uses QC 3.0, but charge slower.
I use original V20 charger, and when charging the status is "quick charging.."
it takes 2 hours from 27% to 100%

not sure about G2. I've never had one.
QC 3.0 might be able to do it technically, but I've never seen a phone that fast in charging yet. Not even the OP3T which every body is saying quickest in charging.

How about your G Flex2? how long it would take to charge to 100%?
G Flex2's battery 3000mAh, right? Same as G2

That grandpa tooks around 2+ hrs to get full charge
But to be fair with the phone, I've never used the original charger of G Flex 2 to charge. I either used my old chargers from previous phones or I plugged it into my laptop to charge it. Let me find the original charger and try it when i get back home
Great
Very fast charge
Delete please.
I have absolutely no complaints with the charging speed. Also, I rarely drop below 40%.
My battery takes forever to charge up!
I just bought a VS995 Verizon Unlocked off the net. Was classified as "almost new - open box", hope I did NOT get a unit with problems. Re-charged it now a total of 5 times and on average (plus or minus 3-5 minutes) it takes approx. 3 hours and 18 minutes. for a full charge 0% to 100% . A few thoughts and questions came to mind while reading all your excellent posts:
1.) I believe he must of lost his quick charger because the one he gave me seems like he bought it off the net. Standard USB charger. So probably not using the quick charge function feature of this phone correct?
2.) Can I goto an electronics store and just copy whatever voltage and amps I need to perform a quick charge? Can someone please POST what the voltages and amps needed for a quick charge 3.0 please.
3.) Anyone have a bad battery or have one go bad after using the wrong charging devices? I was thinking of ordering a new battery BUT they are a little pricey. Anyone know some good outlets to buy them at a fair price?
4.) Does rooting the device and putting one of the ROM's on their cell solve anyone's battery problem? If so which ROM do you recommend?
Overall that is my only gripe about the phone. I love the DAC and for all you music lovers out there try Sirius XM on the LG-V20 and make sure to use Hi-Fi made headphones. I bought myself Bowers and Wilkens P7's, sort of pricey but worth it to me. The other thing is Napster as well the songs you download sound awesome with this DAC. For both of these APPS make sure you go into settings and adjust the quality of the downloads and streaming. Otherwise you could be listening to it with poor quality settings from the get go.
Ok well I appreciate any help or advice on my battery situation!
Thanks in advance to anyone helping me out.

Any charger that says Quick Charge 3.0 would work. I think even QC 2.0 would charge at the same speed, but just less energy efficient.
The difference between qc 2 and 3 is 3 has a variable voltage allowing it to use energy more efficiently.
Excess energy is lost as heat on qc2, the power is reduced in qc3 when the battery starts to get full.
The charge time is the same.
Specs for QC 2 is 5V / 9V/ 12V, specs for QC 3 is
3.2v - 20v dynamic

Droid Turbo Turbo Charge , Quick Charge 2.0 question

So few days ago got the phone , but always charged it through USB port. Now finally tried turbo charger and it definitely isn't "turbo". I know most of those Turbo claims what I saw were just selling strategy , but I'm pretty sure I'm not even getting 1% - 1 minute. Latest Marshmallow OTA.
So , on a relatively new battery , how fast does your phones charge ? You can write with phone turned off and on..
Also looking at the charger it says for output :
Standard output :5V =1.6A
Turbo output :9v=1.6A
Turbo2 output :12v = 1.2A
This deosn't make any sense to me, while raising volts may solve some power losses through cable , amps are what charges your phone faster or slower , and 1.6A , isn't really a big deal not to mention 1.2A. Reading somewhere that quick charge 2,0 supports up to 3amps draw..
I have One Plus one and it's original charger is 2.1A (quick charge 1.0 ) , with custom kernel bumped charging rate all the way up and good cable I'm seeing about 2Amps of charging in real life , or little more than 1% per minute . I was expecting motorola to charge faster or at least even , even though they are 3100 vs 3900mAh batteries.. Not to mention I can easily mod OnePlus One and get same SOT and battery overall as motorola's, while on motorola I'm stuck with stupid locked bootloader . Original idea was to sell OnePlus One because of Motorola, but I don't know now anymore..
The volts and amps listed on an electrical device are typically its max or rated output, NOT what it "always" delivers. That being said, most power supplies will deliver their rated voltage most of the time, but the current is determined by the charged device (through it's effective resistance)... so as long as you run below the rated current, you'd be fine.
Secondly, from what I'm reading, the OPO doesn't have quick-charge technology (ref: https://www.reddit.com/r/oneplus/co...lcomm_quickcharge_20/?st=ix64k1gy&sh=6d7492c9 ) so I'm not sure what you're talking about there. Again, the charger may say 2.1A, but that doesn't mean it's actually delivering that much all the time. I have a relatively old Kindle Fire with a 2.1A charger, but I know it doesn't charge very fast even with that device.
If you want to talk about Volts and Amps, you need to use actual volt/amp meters to see what you're getting.. Note, there is an app for Android (called Ampere) that claims to report amp-rates, but it also has a caveat saying that the current should not be taken as completely accurate, for various reasons.
Lastly, note that QC doesn't actually run when you are at higher charge levels... I think it's above 80% or something? After that level, it returns to "standard charging" mode for this "top-off" phase of the battery charge cycle. So, if you're seeing slow charge rates there, it's to be expected.
The Turbo has a relatively massive battery. Mine takes...somewhere upwards of 3ish hours on turbo charging to replenish.
1 hour 15 minutes
that's what it takes to go from 0 to 100% using Turbo Charger 2.0
Thank you all for answering, this is exactly why I started this thread. Already see here some interesting results!

Thanks! Actually, OnePlus ONE DOES have quick charge 1.0 which is 5v up to 2.1A. Snapdragon 801 supports quick charge 2.0 but OPO didn't implement it with phone. There are billions of topic on this at OPO forum and a lot of people done tests including myself. The problem with OPO is it's very sensitive on cable so it works best with OEM cable and it somehow recognizes it. There is app called OPO charging current so I monitored with it and synapse . Kernel setup hardware to be able to recive very max 2100mA no mather which cable. Stock ONEplus charger. Some cheap cables gave me from 300 - 600 mA max with screen on . I found at home some cable that looked cheap but said charge only, tried and it charged around 1600mA with screen on and around 1800 screen off. Later got Anker 21 AWG and results were even better , aroun 1800-1900mA screen on and close to maximum 2000mA screen off. Phone was charging 1% in less than a minute. Thought turbo can charge at same rate. After all , it's "boosted" lol.
I know it doesn't do quick charge after around 75% , I tried at 30%. Given all that , 1600mA which is maximum I see on the Motorola's charger is not something special if we disregard Voltage..

Because if you charge from 0-100 in 1h 15min, thats around 3.2Amps charging current , while our buddy Einsteindks here gets around 1.3Amps and max amp I see on "rola's charger is 1.6Amps. I'm confused now.
Also can somebody post picof stock droid turbo USB cable shipped in bundle? I think I don't have stock cable, it says right at the plug phone side "be hello". No other labels or anything..

According to your guess-timate and max rated power I see on the charger, that seems about right and realistic guess BUT there also isn't anything TURBO about it. I'ts the average charging speed of every device today (1.5A) which doesn't have any kind of quick charge option. Even quick charge 1.0 is faster with 2.1A at 5v . Thats why I opened this topic, I'm confused.
Only voltage is higher on turbo charger than let's say my OPO charger but amps are lower and voltage doesn't have that much of an impact on charging speed, amps do!
When I have my Turbo in my truck at night, and running about a dozen things at once, in addition to all the background stuff, NO 'regular' charger can keep up with the power demand, and the battery undergoes a insanely slow discharge. By itself, the battery lasts 3 or 4 hours, tops. With the turbocharger, the battery charges at a modest rate, maybe 10% per 30 minutes...while under high demand.

I encourage others to post their charging times so we can compare!
Thanks
Since no other turbo users jumped in...
At the time of starting the topic I have disabled some Verizon's bloatware (completely stock, locked turbo). After reflashing completely stock FW , and with untouched software, droid really did charged turbo fast. More than 1% per minute and around 0-60% for 30min just as advertised for quick charge 2.0 . So if anyone was wondering, that should be benchmark.
On the other hand, phone is almost impossible to charge with any other type of "normal" charger..
My Turbo, running stock MM/root/Xposed with a large load of apps, will charge 20-30% per hour on a normal 1A charger, while lying on the desk with the screen off. It charges at a similar rate via Qi wireless charging. This is plenty for daily overnight charging. My usage habits are such that I usually have 20-40% battery left when I get home from work in the evening.
In a different usage case, when I play Ingress (a real battery eater, screen on + 3D animated graphics + GPS + data) the Qi charger in my car holds discharge to about 5-10% per hour.
I've never had a turbo charger to compare, but I've never found the normal charger or Qi charger to be significantly lacking.

Right, I've also used "normal" charger before. Now, I have all QuickCharge plug chargers -- but I still use Qi wireless charging every day, as does my wife.
I also plug in via USB port on my computer and it charges fine.
okay the way the turbo charging works is that it's like a tier system at very very low charge percentages it works the fastest and slows off after about 60 or 70 percent it just charges like a regular charger all the magic happens at the lower charges. another thing is that unless the cable you are using is total garbage it won't matter at all. it is all the phone and the ac adapter that do the work any variations in the cable will be negligible. I am monitoring my battery through the custom kernel (bhb27 and its app) and it says right now at 81% charge on a turbo charging that I am getting +1172.x mA if my battery was lower this value would be much much higher
lastly I recommend only using the turbo charger when you really need power quickly. if you are just plugging in your phone for the night it makes no sense and will actually be bad for your battery health. the faster it charges the more it heats up and heat is not good for the battery health when I plug my phone in at night I use a .5 amp charger and my phone says that it will need like 8 or 9 hours to charge (this may be exsessive but the quick chargers heat up my phone a lot I also use a 1 and 2 amp charger nearby

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Google Pixel 2 can charge. A higher rating indicates that it charges extremely fast.

I am horrifically disappointed in this device's charging speed.
I was very pleasantly surprised by how fast this phone charges, untill the past few days. Now all the sudden it seems very average. "Charging Rapidly" is not anywhere near as impressive now as it was. Has anyone else experienced this? I want to figure out if it's just the phone (I have seen other slow charging complaints but not this specifically), or if I caused it.
I installed that stock kernel with security pass patch, twrp beta1, Magisk 14.4.2, and Viper4Arise. Pretty confident that it's not any of those things, but everything else is pretty standard.
This is the case with the charger that came with the P2 in box, the older N5x charger, and the usb-c car charger. I know the new P2 one is stronger, but the change is noticable all around.
My 'Charging Rapidly' also does not seem to be all that rapid, using the charger that came in the box and can take quite a while to get to 100%.

It takes hours to get to 100%. I recently got hold of a USB-A to USB-C cable and plugged the phone into my Nexus 6 brick. The difference was astounding. Full charge in about 1.5 hours. It's sickening that I spent the money on this phone only to have it be so disappointing. I'm a diehard Google fanboi but this is ridiculous.
Definitely miss my 1+5 dash charge. Damn that thing was fast.
Some numbers, today I connected my phone at 19% with stock charger.
- 30 min charge: 19% to 56%
- 40 min charge: 19% to 67%
I don't think that's bad, it's definitely not FAST, nor regular. But considering all the issues the 6P had with batteries, I don't really want to charge my battery in less than one hour. (Specially now that the phone has at least 3 years of updates, I'd like to have 90% of battery life or more in 3 years)
I'll have to do another test, something like from 35% to 80% (this would be more real life, I only need a 2nd charge when I'm traveling in a city with a power bank, using Maps and Camera all the time).
Ultra fast charging and wireless charging are some of the features that I care less in the phone. I want some fast charging between 30% and 90%, but I don't require it to be extremely fast.
TL : DR: If you value an ultra fast charging over other things in a phone, definitely skip the Pixel 2.
p2's charging current is capped at 2700ma (could be up to around 3200ma by kernel hax), meanwhile high battery temperature (over 45 Celsius degrees) and others things such as screen state will cap the current more (half or more)
Without those restricts, fully charge time should be around a hour.

With the supplied charger and cable the charging time is very impressive ("Turbo Charge") with a normal QC3.0 charger charge time is still very good but comparable to most other QC3.0 devices.
Something to note is the device does get noticeably warm when using the supplied charger in the "Turbo Charge" mode.
Takes about an hour for me with included charger.

yes i noticed it get warm to hot-ish
isn't that bad for the battery?
moreover i noticed that if you charge while turned off it does not get hot

That's normal because you're not using it, if using while charging it will be hot as your running apps, tasks etc... at the same time. This will increase the heat as sensors will be running also.
Has anyone tried to use other cables that has the same turbo charge effect like the included cable? The included cable is too short, usually I use 2 meters long cable.
I have tried the baseus 5A 40W cable but it only support quick charging and not turbo.
I've tested charging wattage using original 33W charger and original USB cable via specialized USB tester, and I noticed it provides only 25W (about 9.6V/2.65A). It shows "Turbo Charge" indeed, but it's still only 75% efficient. Anyone care to explain this? Is this normal? I've read that only Zoom edition can be charged at 33W, so I expected non-Zoom edition will charge at least with 30W. I tried two other USB cables, and still only 25W. Later today I will try to charge it with Blitzwolf 30W PD charger and see how it goes with that one...
I haven't really tested charge speeds. So far the battery life has been exceptional and the main reason I opted for this phone without the high res screen and refresh rate, as see battery as more essential. I would much prefer charging at a slow speed to preserve battery life. A good app for this is AccuBattery. It measures how many mAh's being charged and discharged after each charge and keeps a graph. It will estimate battery health also.
Yeah I know about AccuBattery, I've been using it in the past. But a real physical tester device is always more precise. I do sw/hw development for a living so I know for a fact. Indeed, battery life is very good because optimized MIUI and pretty big battery, but it would be even better if charging speed was also up to the specs. Meanwhile I've tested charging speed using Blitzwolf 30W PD2.0 charger (K30Pro should support PD3.0 and be backward compatible), and situation is even worse - only about 15-16W at QC3.0 I believe. So no Turbo Charge was initiated. I mean 25W with original charger is still good, but I expected advertised charging speed. I'll do more tests when I catch some time.
Thats normal, because it don't charge all the time with 30W. Compare it with WARP Charge 30T it is faster. OnePlus 8 got 30W and 4300 mAh, F2 Pro is faster with bigger bettery but it's almost the same.
How old is your Blitzwolf charger?
I know it shouldn't charge @30W above 80-90%, but sure it should at 20-ish where I'm at about now. It's also not even cool to the touch, so there's no apparent reason to slow it to 25W. My Blitzwolf charger is about a year old, but I only used it couple of times, so it should be as good as new.

Batteries don't like heat but it is actively monitored and it will slow down charging when it crosses temperature threshold.
That's why I mentioned my phone is not even cool to the touch (let alone hot), so my case is not temperature related. I'll try to charge it while turned off, though it was pretty much in idle doing nothing when I did the test, ie. not stressed at all by any factor. All in all, I mean if everyone else gets 25W out of original charger, I won't bother anymore. Also, if it charges from 10-90% in around 1 hour, I won't waste any more time on this either, since it's good enough for me. I was just curious why it charges at 25W, when 30W (and 33W for Zoom edition) was advertised. Altough it wouldn't be the first time something was advertised at launch, and not achievable in real-case scenario.

Fun fact: phone doesn't charge when powered off?! That's a first. Is it just me, or am I getting too old? For the whole time I'm talking about my Redmi, not to confuse it with Poco, if that matters at all. Maybe Poco works differently.
On my Huawei device you also can not turn off an charge but this starts with Android 10.
takes about 1 hour and 20 minutes for me, I think the high temperature here, summer season, is the reason for this slow charging speed.
From 20-100% in about an hour. Few minutes less actually. Battery is big, that's all ok.
F2 turn off and are dead with 0% (can't turn on). Timer 60 min. and after 60 min. I got 96% with original charger. The phone don't turn on, like it always do.
@Burs a friend told me "on my Anker charger I only can use PD over the third usb port, with the type c port it will charge over QC 3.0 and not over PD" maybe thats why you get ~16W?
When my Redmi was turned off completey, it was hooked up to my USB tester for about a minute. I doubt it would trigger after some minutes, and only then start charging. For the whole time it was connected, I was getting 5V / 0.015A readings on the display. That's pretty much USB tester drawing the power from the phone battery, not the charger! So that would mean charging was completely disabled making the phone behave as a power bank lol. Weird enough, right?
My Blitzwolf charger has only two ports. One PD2.0 (USB-C) and one QC3.0 (USB-A). I've tried three sets of USB cables (one even 5A) on both ports, and best I could get out of it was about 15W. I think I'll have to order another one with PD3.0 and Turbo Charge compatibility.
Heh I'm planning on just using my old 1A slow chargers because they're dotted around the house and work, will probably not even plug fast charger in. Magnetic cables are just so convenient.
