Latedroid Devs:

I hope this finds you well and in excellent spirits conducive to problem solving! I hope you are also in reach of your reading glasses; as in an effort to include all the information you will need I have written what is--I am almost certain--a report of above average length. However, I have separated the report into different sections to ensure ease of reading. This report is similar to one posted by another user almost a month ago (link: http://bit.ly/u8qP4e), but I am not convinced it is the same issue. Regardless, the previous report fails to adequately communicate the severity of the issue and provides almost no information that might assist in solving the problem (no offense to author intended).

:::::::::: INTRODUCTION ::::::::::

Before I say anything else, I want to thank you for making an absolutely amazing product; JuiceDefender is without a doubt the best $5 I have spent on my phone. Under heavy use, my battery lasts 2-3x longer, and uses almost no juice if it's not in use (the way it should be). Succinctly, I love your app; I was even asked on another forum if I worked for Latedroid because how often I praise its virtues. I wanted to mention this to make clear my motivation in writing this report. It's not because I am angry with any of you or because I think your product is the worst invention since reality television shows. On the contrary, I consider JD to be one of the most crucial applications on my phone, and I really--REALLY--want it working again, as do many others. It is my hope that in doing this, I will help this be accomplished swiftly.

:::::::::: DEVICE INFORMATION ::::::::::

NAME: LG Revolution
MODEL #: VS910 4G
OS: Android 2.3.4 (Gingerbread) [ROOTED]
BASEBAND: VS910ZV7-M7X30-AABBQMLYM
KERNEL: 2.6.35.7-perf
SW Version: VS910ZV7
JD Version: 3.8.3Beta (Ultimate) [AOSP Helper successfully installed]

:::::::::: THE PROBLEM ::::::::::

<<< TLDR >>>
In a nutshell, Juice Defender is "disabling" 3G/4G (hereafter referred to collectively as "data"), and restarting the phone appears to be the only means of restoring the data connection. Considering that JD worked almost flawlessly on my Revolution until it was upgraded from Froyo to GingerBread, I am inclined to think the problem may be a compatibility issue in GB.

<<< Isolating the Issue >>>
How do I know it's JuiceDefender causing the problem? I and many other people (most more knowledgeable than me) performed a fair amount of troubleshooting to ensure we were isolating the problem correctly and ruling out any extraneous variables. We've performed the standard tech procedures of manually enabling/disabling data, airplane mode, JD, etc. (countless times) and tried many other things in our desperation, all to no avail. Even disregarding all that, the problem ceases to exist when JD is disabled or uninstalled, so we're pretty certain we're not crazy. =]

<<< Occurrence >>>
Everything appears to function normally when the phone is first turned on/rebooted, but once the screen is turned off (which, in my case, disables both data and Wi-Fi), everything goes to hell. I could change the settings to not disable internet connections when I turn the screen off, but the problem would still occur the first time JD is triggered to turn off the data network. That is why there has been so much variance vis-à-vis when the problem occurs--we all have different triggers/controls/etc that would affect when data was being turned off for the first time. Put simply:

0) 4G/3G (data) works only as long as it hasn't been turned off by JuiceDefender. After JD disables data for the first time, it is completely disabled (though Wi-Fi still works) and can only be restored by restarting the phone.

<<< Troubleshooting Information >>>
To make matters worse, JuiceyDeucey not only blocks me from the interwebs, it taunts me! Don't believe me? Read on! I've included the bulk of the remaining information in these bullet points to avoid this becoming a novella.

1) 4G icon in notification bar is replaced with 3G (I know with certainty that I am in a 4G area).
----1a) 4G is still listed under [Settings > About Phone > Status > Network Type & Strength] (-103dBm) along with 1x (-96dBm).
2) The JD 2x1 widget frequently varies in how it reports the status of the data network, and it is often inconsistent with the actual system settings, the JD info panel in the pulldown menu, or both.
----2a) Using the JD Data Toggle widget to force disable data does not actually disable anything (nor does it remove the 3G icon from the notification bar).
----2b) Using the JD Data Toggle widget to force enable data does not cause data to resume functioning normally.
3) Disabling data within the phone's Mobile Network Settings does not remove the 3G icon from the notification bar (nor does reenabling it restore connectivity).
----3a) Same as #3. Only a system restart resumes data connectivity.
----3b) Completely disabling JuiceDefender also does not resolve the issue, unless it is disabled before it has a chance to turn off data (as mentioned in #0).
----3c) Enabling the [Mobile Data AutoFix] within JuiceDefender initially (seemingly) does nothing, but then disables data completely (but there's no 3G icon taunting me).
4) Data (including 4G) functions normally if JuiceDefender is disabled or uninstalled.
----4a) Data (including 4G) functions normally alongside JuiceDefender ONLY when all JD settings pertaining to control of the data network are disabled (auto sync not included).
----4b) The issue does not occur if the [Network Mode] within the phone's settings is changed to [CDMA Only]. With 4G disabled, everything appears to function normally, so it appears the problem lies within JD's attempts to switch to/from 4G.
5) This problem occurs both with and without AOSP Helper installed. Problem persists after formatting both the internal and external sdcard, performing a factory reset, and then installing JuiceDefender on a perfectly clean system.

<<< JuiceDefender Logs >>>
I replicated the issue and created several logs using the feature within the Beta version of JuiceDefender. I am sending several logs because I don't know exactly how the logging feature works, and I did not want to risk a crucial instant being absent. Unfortunately, this means there's likely a good bit of redundancy within the logs, and I apologize to whomever is responsible for sorting through them. Please note that I stated above that AOSP Helper was successfully installed, which it was, but these logs were made on a recently reset phone and I have not reinstalled the AOSP Helper at this point.

I will include a brief explanation of the circumstances surrounding the time when the log was captured. There are a total of six (6) logs, which I will number in order of their occurrence. For your convenience, I have sent all six in a single E-Mail to [logs@latedroid.com] with the label "[LOG] [REVOLUTION] [DATA ISSUE]" including the attached .txt files and the content generated in the body of the email when a log is created. I hope you find this information helpful in determining the source of this problem.

:::::::::: CONCLUSION ::::::::::

I'd like to clarify that I am writing this report not strictly for myself, but on behalf of the dozens of LG Revolution owners within the XDA-Developers community. Many of us depend on JuiceDefender--including a large number who have purchased the Plus or Ultimate versions--to ensure our batteries will last an entire day (or two, or three) instead of 8 hours. Certainly you can understand our frustration when you make such an outstanding application, we purchase it and get hooked on it, and then suddenly take it away without warning! We even considered "Occupying" your front lawn, but we decided it was too cold outside. ;-)

But seriously, there really are a number of people with Revolutions who tried JD but have yet to purchase JD Plus/Ultimate because of the compatibility issues; if you can fix this, then I'll finally be vindicated for my vehement support. I will encourage all of these Revolution owners (both current and potential customers) to follow the progress of this report and provide any information/assistance needed for a swift resolution of this problem and a return of our phones to their former glory. Just let us know what you need--logs, configuration schemes, TPS Reports, banana pudding pie--anything that's not too illegal, and I or someone else will be sure to avail it to you.

You have my most sincere appreciation for your time and consideration.

Sincerely,

James

Hej, I'm using Juice Defender Plus on my SGS2. I've run into three "problems" I'd like to address:
1) The settings for the quick box (disable it, in my case) revert every time I open the settings, rendering this feature kind of useless.
2) Under Night-Schedule the button "Airplane" reverts to "off" every time I open the settings, also rendering this kind of useless.
3) I'm using the location-based WiFi. While it works quite nicely when I'm at home or other places I trained JD to connect wo WiFi, it's kind of annoying that every time I turn on the screen it enables WiFi to check for Accesspoints. I'm not quite sure whether it's a misconfiguration or a misconception. If it's my fault I'm more than happy to learn how to configure JD so that it only enables WiFi when I'm in reach of known Access points anyways.

That said and aside I'm really enjoying JD.

I'm running JD 3.9.4 on an EVO 4G with Cyanogen 7.2 rc1 (Gingerbread).

I set the threshold to 1KB/5s, 2min on WiFi and 3G and lined up 10 podcasts to download. After 2 minutes, JD kills connectivity and Doggcatcher attempts and fails to download the remaining podcasts.

I have not found a workaround I'm happy with, but for now I have 4PM as my peak hour with all radios on, which coincides with Doggcatcher's automatic update. Unfortunately, Doggcatcher checks for episodes throughout the day and can't maintain a connection to allow new episodes to come in during off-peak hours.

I saw another thread like this under "bugs," but it was marked "complete" without mention of any solution. If you have/had a problem like mine, please throw this a vote.

Commuting with public transportation every day is a hassle. Thankfully some Smartphone's apps allow to check (automatically) for train delays and such. I would therefore prefer more than one peak time a day for stable connection, e.g. one in the morning and another one in the afternoon. To get every apps bit of information can save a lot of frustration ;)

Right now i am using the weekend settings set to mon-fri for an additional evening peak, but that can't be the answer :-)

So, two or more peak times during a day would be just wonderful!

Thanks!
(JD Ultimate, HTC EVO 3D)

I am on 3.9.4beta and have the following enabled settings with UJ:
controls: Wifi (Auto disable), AutoSync (Ping)
keep on: Wifi
location

nothing more.

As you see I only use JD to manage my wifi based on location and keep it enabled if available, but sometimes wifi automatically disables if screen goes off while the rooter is in 1-2m distance. In the wifi advanced settings I have 'Keep Wifi on during sleep' set to Always and if I disable JD it keeps connected.
imho the 'keep on wifi' setting is not 100% working. do you need any more details to evaluate this?

Juice Defender does a great job at maximizing battery life, usually doubling my battery life! A natural consequence of this is that my phone is slower to complete some actions (either through CPU scaling, data toggling, etc.) A very elegant approach to getting the best of both worlds, I think, would be to allow for target times - that is times you want your battery to last until.

For example, I know that I can plug my phone in by 7pm every day. By setting this as a target JD would scale the settings appropriately to make sure the battery lasts until then with the minimum reduction necessary. There is no point in sacrificing performance when I don't need the battery to last until midnight!

Thanks for the great product, Istvan.
